(23) FIG. 1 illustrates a method 1000 for in-situ accumulation of one or more substances from a liquid environment 50.

(24) The method 1000 has an act of placing 1100 a cartridge 700 with a sorbent 750 in the liquid environment 50. The cartridge 700 can be placed in a river, a sea, a lake, a drilled bore in soil, ground water or any other kind of liquid environment 50.

(25) The method 1000 has a further act of driving 1200 a liquid volume through the sorbent 750.

(26) The sorbent 750 is designed for adsorbing or absorbing certain substances or substance groups. If the liquid volume contains one or more of the certain substances or substance groups, then these substances or substance groups will be adsorbed or absorbed by the sorbent 750.

(27) The method 1000 has a further act of repeating 1300 the act of driving 1200 as a function of time.

(28) The sorbent 750 will accumulate substances or substance groups during each act of driving 1200 provided that these substances or substance groups are present in the liquid environment 50. Because the number of acts of driving 1200 is known then the total liquid volume through the sorbent 750 is known. The sorbent 750 is afterwards tested for the total accumulation of the substances or the substance groups and from this one can determine whether the amount of substances or substance groups in the total liquid volume was above or below a threshold value.

(29) The function of time may cause the act of repeating 1300 the act of driving 1200 one or more times between 4 PM and 8 AM the next day.

(30) The function of time may cause the act of repeating 1300 the act of driving 1200 one or more times per day.

(31) The function of time may randomly cause the act of repeating 1300 the act of driving 1200.

(32) FIG. 2 illustrates another embodiment of a method 1000 for in-situ accumulation of one or more substances from a liquid environment 50.

(33) The method 1000 has an act of placing 1100 a cartridge 700 with a sorbent 750 in the liquid environment 50. The cartridge 700 can be placed in a river, a sea, a lake, a drilled bore in soil, ground water or any other kind of liquid environment 50.

(34) The method 1000 has a further act of driving 1200 a liquid volume through the sorbent 750, wherein the act of driving 1200 is performed by changing a volume of a chamber 500 having an initial chamber volume 510i in liquid connection 600 with the cartridge 700.

(35) The sorbent 750 is designed for adsorbing or absorbing certain substances or substance groups. If the liquid volume contains one or more of the certain substances or substance groups, then these substances or substance groups will be adsorbed or absorbed by the sorbent 750.

(36) The act of driving 1200 includes an act of resetting 1250 the chamber 500 to the initial chamber volume 510i. Thereby, the chamber 500 can be smaller and it is easier control the chamber volume 510, when the chamber volume 510 does not have to increase with each act of driving 1200.

(37) The method 1000 has a further act of repeating 1300 the act of driving 1200 as a function of time.

(38) The sorbent 750 will accumulate substances or substance groups during each act of driving 1200 provided that these substances or substance groups are present in the liquid environment 50. Because the number of acts of driving 1200 is known then the total liquid volume through the sorbent 750 is known. The sorbent 750 is afterwards tested for the total accumulation of the substances or the substance groups and from this one can determine whether the amount of substances or substance groups in the total liquid volume was above or below a threshold value.

(39) The function of time may cause the act of repeating 1300 the act of driving 1200 one or more time between 4 PM and 8 AM the next day.

(40) The function of time may cause the act of repeating 1300 the act of driving 1200 one or more times per day.

(41) The function of time may randomly cause the act of repeating 1300 the act of driving 1200.

(42) The act of repeating 1300 includes an act of hibernating 1350 as a function of time between the acts of driving 1200.

(43) The act of hibernating 1350 makes the method 1000 more energy-efficient.

(44) FIG. 3 illustrates an embodiment of a system 10 for in-situ accumulation of substances.

(45) FIG. 3A discloses the system 10 without a shell 140 and FIG. 3B discloses the same system 10 with a cross-section of a shell 140.

(46) The system 10 has a frame arrangement 100 supporting a not shown actuator 20. The actuator is configured for driving the spindle 30. The spindle 30 defines a displacement axis 34 which extends in the same direction as the spindle 30.

(47) An end of the spindle 30 is connected to a flange 300, the flange 300 has a neck 320 extending towards the not shown actuator 20. The neck 320 has a not shown internal thread 322 for engaging with an external thread 36 of the spindle 30. The neck 320 which has a substantial length ensures that the displacement of the flange 300 is precise with little to no twisting or flexing.

(48) The flange 300 has a flange periphery 310 defining a shape complementary to the shell 140.

(49) The flange 300 supports two pistons 400, each piston 400 being connected to the flange 300 by the piston foot 440 which is secured to the flange 300 using screws. Each piston 400 has a piston shaft 410 extending from the piston foot 440 to the piston crown 420.

(50) Each piston crown 420 being configured to operate in a chamber 500. The complementary piston crowns 420 and chambers 500 define a chamber volume 510 as a function of the displacement of the piston crown 420. In FIG. 1B, the chamber volume is at a minimum chamber volume 512 which will typically be the initial chamber volume 510i.

(51) Each chamber 500 has a chamber wing 530 which is used to fixate the chamber 500 to a chamber plate 110. The chamber plate 110 is in FIG. 3B connected to the shell 140 and thereby the chamber 500 is secured relative to the frame arrangement 100.

(52) Each chamber 500 has a chamber channel 520 adapted for displacement of the piston crown 420.

(53) The chamber 500 is in a liquid connection 600 with a cartridge 700. The liquid connection 600 has an exhaust 610 with an exhaust valve 620 and a cartridge valve 630 near the cartridge 700.

(54) Each cartridge 700 comprises a cartridge outlet 730 connected to the liquid connection 600, an inlet 710 in direct contact with liquid environment 50 when in intended use.

(55) The cartridges 700 have two different sorbents 7501, 75011 for accumulation of two different substances or two different substance groups.

(56) The cartridges 700 are stabilised by a cartridge plate 120 fixed to the frame arrangement 100 by the shell 140.

(57) The shell 140 has diffusion gaps 142 for diffusion of liquid from the liquid environment 50 into the system 10.

(58) The system 10 will accumulate substances by actuating the spindle 30 causing the flange 300 to be displaced parallel to the displacement axis 34. The piston crowns 420 supported by the flange 300 will likewise displace parallel to the displacement axis 34 towards the frame arrangement 100. This will cause the chamber volume 510 to increase causing a negative pressure in the chamber 500 relative to the liquid environment 50. The negative pressure will drive a liquid volume, equal to the change in the chamber volume 510, through the sorbent.

(59) The exhaust valve 620 in the exhaust 610 ensures that no liquid enters the chamber 500 through the exhaust 610.

(60) The sorbents 750 will act as a resistance for the liquid passing through and therefore it may take ten minutes for the chamber 500 to be filled with liquid. The system 10 may hibernate during the filling of the chamber 500. The sorbents 750 will absorb or adsorb substances from the passing liquid provided that the liquid contains substances that the sorbents 750 are adapted to absorb or adsorb.

(61) The liquid may be rejected from the chamber 500 by resetting the chamber volume 510 to the initial chamber volume 510i by returning the piston crown 420 to the initial position which typically is where the chamber 500 has a minimum chamber volume 512, i.e. where the piston crown 420 is close to the liquid connection 600.

(62) The system 10 is designed to have a small axial extent from the displacement axis 34, thereby enabling the system 10 to be inserted into a drilled bore in soil.

(63) The space within the shell 140 is filled with liquid from the liquid environment 50, thereby the flange 300 will be exposed to the same pressure on both sides relative to the displacement axis 34 which will increase the precision of the displacement of the flange 300.

(64) FIG. 4 illustrates a cross section of an embodiment of a system 10 for in-situ accumulation of substances.

(65) The system 10 has a frame arrangement 100 supporting an actuator 20 and a battery 40 powering the actuator 20. The actuator is configured for driving the spindle 30. The spindle 30 defines a displacement axis 34 which extends in the same direction as the spindle 30.

(66) An end of the spindle 30 is connected to a flange 300, the flange 300 has a neck 320 extending towards the actuator 20. The neck 320 has an internal thread 322 for engaging with an external thread 36 of the spindle 30. The neck 320 which has a substantial length ensures that the displacement of the flange 300 is precise with little to no twisting or flexing.

(67) The flange 300 has a flange periphery 310 defining a shape complementary to the shell 140.

(68) The flange 300 supports two pistons 400, each piston 400 being connected to the flange 300 by the piston foot 440, which is secured to the flange 300 using screws. Each piston 400 has a piston shaft 410 extending from the piston foot 440 to the piston crown 420.

(69) Each piston crown 420 being configured to operate in a chamber 500. The complementary piston crowns 420 and chambers 500 define a chamber volume 510 as a function of the displacement of the piston crown 420.

(70) Each chamber 500 has a chamber wing 530 which is used to secure the chamber 500 to a chamber plate 110.

(71) Each chamber 500 has a chamber channel 520 adapted for displacement of the piston crown 420.

(72) The chamber 500 is in a liquid connection 600 with a cartridge 700. The liquid connection 600 has an exhaust 610 with an exhaust valve 620 and a cartridge valve 630 near the cartridge 700.

(73) Each cartridge 700 comprises a cartridge outlet 730 connected to the liquid connection 600 and an inlet 710 in direct contact with liquid environment 50, when in intended use.

(74) The cartridges 700 have two different sorbents 7501, 75011 for accumulation of two different substances or two different substance groups.

(75) The cartridges 700 are stabilised by a cartridge plate 120 fixed to the frame arrangement 100 by the shell 140.

(76) The shell 140 has diffusion gaps 142 for diffusion of liquid from the liquid environment 50 into the system 10.

(77) The system 10 will accumulate substances by actuating the spindle 30 causing the flange 300 to be displaced parallel to the displacement axis 34. The piston crowns 420 supported by the flange 300 will likewise displace parallel to the displacement axis 34 towards the frame arrangement 100. This will cause the chamber volume 510 to increase causing a negative pressure in the chamber 500 relative to the liquid environment 50. The negative pressure will drive a liquid volume equal to the change in the chamber volume 510 through the sorbent.

(78) The exhaust valve 620 in the exhaust 610 ensures that no liquid enters the chamber 500 through the exhaust 610.

(79) The sorbents 750 will act as a resistance for the liquid passing through and therefore it may take ten minutes for the chamber 500 to be filled with liquid. The system 10 may hibernate during the filling of the chamber 500. The sorbents 750 will absorb or adsorb substances from the passing liquid provided that the liquid contains substances that the sorbents 750 are adapted to absorb or adsorb.

(80) The liquid may be rejected from the chamber 500 by resetting the chamber volume 510 to the initial chamber volume 510i by returning the piston crown 420 to the initial position which typically is where the chamber 500 has a minimum chamber volume 512, i.e. where the piston crown 420 is close to the liquid connection 600.

(81) The system 10 is designed to have a small axial extent from the displacement axis 34, thereby enabling the system 10 to be inserted into a drilled bore in soil.

(82) FIG. 5 illustrates a top side view of a system 10 for in-situ accumulation of substances. The system 10 has a frame arrangement 100 supporting a not shown actuator 20. The actuator 20 is configured for driving the spindle 30. The spindle 30 defines a displacement axis 34 which extends in the same direction as the spindle 30.

(83) The spindle 30 is connected to a flange 300 by a ball screw 32 for reducing slackness.

(84) The flange 300 has a flange periphery 310 defining a shape complementary to a shell 140 being part of the frame arrangement 100 and radially surrounding the spindle 30.

(85) The system is disclosed without the shell 140, however, the shell 140 must be present for this specific embodiment to work as the system 10 would otherwise collapse.

(86) The flange 300 supports four pistons 400, each piston 400 being connected to the flange 300 by a piston foot 440. The piston foot 440 is secured to the flange 300 using screws. Each piston 400 has a piston shaft 410 extending from the piston foot 440 to the piston crown 420.

(87) The flange periphery 310 further comprises four indents 312 (two are visible) for engaging with four rods 140 (three are visible) supported longitudinally to the not shown shell 140.

(88) Each piston crown 420 is configured to operate in a chamber 500. The piston crowns 420 and chambers 500 define a chamber volume 510 as a function of the displacement of the piston crown 420.

(89) Each chamber 500 has a chamber wing 530 which is used to secure the chamber 500 to a first and a second chamber plate 110I, 110II by clamping. The chamber plates 110I, 110II are connected to the not shown shell 140, and thereby the chamber 500 is secured relative to the frame arrangement 100.

(90) Each chamber 500 has a chamber channel 520 adapted for displacement of the piston crown 420.

(91) Each chamber 500 is in a liquid connection 600 with a cartridge 700. The liquid connection 600 has an exhaust 610 with an exhaust valve 620 and a cartridge valve 630 near the cartridge 700.

(92) Each cartridge 700 comprises a cartridge outlet 730 connected to the liquid connection 600, an inlet 710 in direct contact with a liquid environment 50 when in intended use. The inlet has inlet wings 720.

(93) Each cartridge 700 has a sorbent 750 (not shown) for accumulation of one or more substances or substance groups.

(95) The system 10 comprises an end plate 200 having a spindle recess 210 for engaging with the spindle 30.

(96) The end plate 200 further comprises a shell recess 230 for engaging with the shell 140, when in intended use. The shell recess 230 forms, in this embodiment, a circular channel.

(97) The system 10 accumulates substances by actuating the spindle 30 causing the flange 300 to be displaced parallel to the displacement axis 34. The piston crowns 420 supported by the flange 300 will likewise displace parallel to the displacement axis 34 away from the frame arrangement 100. This will cause the chamber volume 510 to increase causing a negative pressure in the chamber 500 relative to the liquid environment 50. The negative pressure will drive a liquid volume equal to the change in the chamber volume 510 through the sorbent 750.

(98) The exhaust valve 620 in the exhaust 610 ensures that no liquid enters the chamber 500 through the exhaust 610.

(99) The sorbent 750 will act as a resistance for the liquid passing through and therefore it may take ten minutes for the chamber 500 to be filled with liquid. The system 10 may hibernate during the filling of the chamber 500. The sorbent 750 will absorb or adsorb substances from the passing liquid provided that the liquid contains substances that the sorbent 750 is adapted to absorb or adsorb.

(100) The liquid may be rejected from the chamber 500 by resetting the chamber volume 510 to the initial chamber volume 510i or by returning the piston crown 420 to the initial position which typically is where the chamber 500 has a minimum chamber volume 512, i.e. where the piston crown 420 is close to the liquid connection 600.

(101) FIG. 6 illustrates a system 10 for in-situ accumulation of substances.

(102) The system 10 is identical to the system 10 disclosed in FIG. 5, but the shell 140 with diffusion gaps 142 is shown. The shell 140 is connected to the frame arrangement 100 by clamps 180 and the shell 140 is inserted into the shell recess 230 of the end plate 200.

(103) The space within the shell 140 is filled with liquid from the liquid environment 50 thereby the flange 300 will be exposed to the same pressure on both sides relative to the displacement axis 34 which will increase the precision of the displacement of the flange 300.

(104) FIG. 7 illustrates an embodiment of a system 10 for in-situ accumulation of substances.

(105) FIG. 7A discloses the system 10 without a shell 140 and FIG. 7B discloses the same system 10 with a cross-section of a shell 140.

(106) The system 10 has a frame arrangement 100 supporting a not shown actuator 20. The actuator is configured for driving the spindle 30. The spindle 30 defines a displacement axis 34 which extends in the same direction as the spindle 30.

(107) An end of the spindle 30 is connected to a flange 300, the flange 300 has a neck 320 extending towards the not shown actuator 20.

(110) Each piston crown 420 being configured to operate in a chamber 500. The complementary piston crowns 420 and chambers 500 define a chamber volume 510 as a function of the displacement of the piston crown 420. In FIG. 7B the chamber volume is at a minimum chamber volume 512 which will typically be the initial chamber volume 510i.

(111) Each chamber 500 has a chamber wing 530 which is used to fixate the chamber 500 to a chamber plate 110. The chamber plate 110 is in FIG. 7B connected to the shell 140 and thereby the chamber 500 is fixated relative to the frame arrangement 100.

(115) The cartridges 700 have to different sorbents 7501, 75011 for accumulation of two different substances or two different substance groups.

(116) The cartridges 700 are stabilised by a cartridge plate 120 fixed to the frame arrangement 100 by the shell 140.

(117) The shell 140 has diffusion gaps 142 for diffusion of liquid from the liquid environment 50 into the system 10.

(118) The system 10 will accumulate substances by actuating the spindle 30 causing the flange 300 to be displaced parallel to the displacement axis 34. The piston crowns 420 supported by the flange 300 will likewise displace parallel to the displacement axis 34 towards the frame arrangement 100. This will cause the chamber volume 510 to increase causing a negative pressure in the chamber 500 relative to the liquid environment 50. The negative pressure will drive a liquid volume, equal to the change in the chamber volume 510, through the sorbent.

(119) The exhaust valve 620 in the exhaust 610 ensures that no liquid enters the chamber 500 through the exhaust 610.

(120) The sorbents 750 will act as a resistance for the liquid passing through and therefore it may take 10 minutes for the chamber 500 to be filled with liquid. The system 10 may hibernate during the filling of the chamber 500. The sorbents 750 will absorb or adsorb substances from the passing liquid provided that the liquid contains substances that the sorbents 750 are adapted to absorb or adsorb.

(121) The liquid may be rejected from the chamber 500 by resetting the chamber volume 510 to the initial chamber volume 510i by returning the piston crown 420 to the initial position which typically is where the chamber 500 has a minimum chamber volume 512, i.e. where the piston crown 420 is close to the liquid connection 600.

(122) The system 10 is designed to have a small axial extent from the displacement axis 34, thereby enabling the system 10 to be inserted into a drilled bore in soil.

(123) The space within the shell 140 is filled with liquid from the liquid environment 50 thereby the flange 300 will be exposed to the same pressure on both sides relative to the displacement axis 34 which will increase the precision of the displacement of the flange 300.

(124) FIG. 8 illustrates a cross section of an embodiment of a system 10 for in-situ accumulation of substances.

(125) The system 10 has a frame arrangement 100 supporting an actuator 20 and a battery 40 powering the actuator 20. The actuator is configured for driving the spindle 30. The spindle 30 defines a displacement axis 34 which extends in the same direction as the spindle 30.

(126) An end of the spindle 30 is connected to a flange 300, the flange 300 has a neck 320 extending towards the actuator 20. The neck 320 has an internal thread 322 for engaging with an external thread 36 of the spindle 30. The neck 320 which has a substantial length ensures that the displacement of the flange 300 is precise with little to no twisting or flexing.

(127) The flange 300 has a flange periphery 310 defining a shape complementary to the shell 140.

(128) The flange 300 supports two pistons 400, each piston 400 being connected to the flange 300 by the piston foot 440 which is secured to the flange 300 using screws. Each piston 400 has a piston shaft 410 extending from the piston foot 440 to the piston crown 420.

(129) Each piston crown 420 being configured to operate in a chamber 500. The complementary piston crowns 420 and chambers 500 define a chamber volume 510 as a function of the displacement of the piston crown 420.

(130) Each chamber 500 has a chamber wing 530 which is used to fixate the chamber 500 to a chamber plate 110.

(131) Each chamber 500 has a chamber channel 520 adapted for displacement of the piston crown 420.

(132) The chamber 500 is in a liquid connection 600 with a cartridge 700. The liquid connection 600 has an exhaust 610 with an exhaust valve 620 and a cartridge valve 630 near the cartridge 700.

(133) Each cartridge 700 comprises a cartridge outlet 730 connected to the liquid connection 600, an inlet 710 in direct contact with liquid environment 50 when in intended use.

(134) The cartridges 700 have two different sorbents 7501, 75011 for accumulation of two different substances or two different substance groups.

(135) The cartridges 700 are stabilised by a cartridge plate 120 fixed to the frame arrangement 100 by the shell 140.

(136) The shell 140 has diffusion gaps 142 for diffusion of liquid from the liquid environment 50 into the system 10.

(137) The system 10 will accumulate substances by actuating the spindle 30 causing the flange 300 to be displaced parallel to the displacement axis 34. The piston crowns 420 supported by the flange 300 will likewise displace parallel to the displacement axis 34 towards the frame arrangement 100. This will cause the chamber volume 510 to increase causing a negative pressure in the chamber 500 relative to the liquid environment 50. The negative pressure will drive a liquid volume equal to the change in the chamber volume 510 through the sorbent.

(138) The exhaust valve 620 in the exhaust 610 ensures that no liquid enters the chamber 500 through the exhaust 610.

(139) The sorbents 750 will act as a resistance for the liquid passing through and therefore it may take ten minutes for the chamber 500 to be filled with liquid. The system 10 may hibernate during the filling of the chamber 500. The sorbents 750 will absorb or adsorb substances from the passing liquid provided that the liquid contains substances that the sorbents 750 is adapted to absorb or adsorb.

(140) The liquid may be rejected from the chamber 500 by resetting the chamber volume 510 to the initial chamber volume 510i by returning the piston crown 420 to the initial position which typically is where the chamber 500 has a minimum chamber volume 512, i.e. where the piston crown 420 is close to the liquid connection 600.

(141) The system 10 is designed to have a small axial extent from the displacement axis 34, thereby enabling the system 10 to be inserted into a drilled bore in soil.

(142) The space within the shell 140 is filled with liquid from the liquid environment 50 thereby the flange 300 will be exposed to the same pressure on both sides relative to the displacement axis 34 which will increase the precision of the displacement of the flange 300.

(143) FIG. 9 illustrates a system 10 for in-situ accumulation of substances.

(144) The system 10 has a frame arrangement 100 supporting a not shown actuator 20. The actuator is configured for driving the spindle 30. The spindle 30 defines a displacement axis 34 which extends in the same direction as the spindle 30.

(145) The spindle 30 is connected to a flange 300 by a ball screw 32 for reducing slackness.

(146) The flange 300 has a flange periphery 310 defining a shape complementary to a shell 140 being part of the frame arrangement 100 and radially surrounding the spindle 30.

(147) The shell 140 has diffusion gaps 142 for diffusion of liquid between the liquid environment 50 and the system 10.

(148) The flange 300 supports four pistons 400, each piston 400 being connected to the flange 300 by the piston foot 440 which may be secured to the flange 300 using screws. Each piston 400 has a piston shaft 410 extending from the piston foot 440 to the piston crown 420 and the piston crown 420 has a piston ring 430.

(149) The flange periphery 310 further comprises four not shown indents 312 for engaging with four rods 150 (only one is shown) longitudinally supported to the shell 140.

(150) Each piston crown 420 is configured to operate in a chamber 500.

(151) In the present figure only one piston crown 420 operates in the chamber 500. The piston crown 420 and chamber 500 define a chamber volume 510 as a function of the displacement of the piston crown 420.

(152) The chamber 500 has a chamber wing 530 which is used to fixate the chamber 500 to a first and a second chamber plate 110I, 110II by clamping. The chamber plates 110I, 110II are connected to the shell 140, and thereby the chamber 500 is fixated relative to the frame arrangement 100.

(153) The chamber 500 has a chamber channel 520 adapted for displacement of the piston crown 420.

(154) The chamber 500 is in a liquid connection 600 with a cartridge 700. The liquid connection 600 has an exhaust 610 with an exhaust valve 620 and a cartridge valve 630 near the cartridge 700.

(155) The cartridge 700 comprises a cartridge outlet 730 connected to the liquid connection 600, an inlet 710 in direct contact with liquid environment 50 when in intended use. The inlet has inlet wings 720.

(156) The cartridge 700 has a sorbent 750 for accumulation of one or more substances or substance groups.

(157) The cartridges 700 are stabilised by a cartridge plate 120 fixed to the frame arrangement 100 by the shell 140.

(158) The system 10 comprises an end plate 200 having a (not shown) spindle recess 210 for engaging with the spindle 30.

(159) The end plate 200 further comprises (not shown) a shell recess 230 for engaging with the shell 140.

(160) The system 10 accumulates substances by actuating the spindle 30 causing the flange 300 to be displaced parallel to the displacement axis 34. The piston crowns 420 supported by the flange 300 will likewise displace parallel to the displacement axis 34 away from the frame arrangement 100. This will cause the chamber volume 510 to increase causing a negative pressure in the chamber 500 relative to the liquid environment 50. The negative pressure will drive a liquid volume equal to the change in the chamber volume 510 through the sorbent 750.

(161) The exhaust valve 620 in the exhaust 610 ensures that no liquid enters the chamber 500 through the exhaust 610.

(162) The sorbent 750 will act as a resistance for the liquid passing through and therefore it may take ten minutes for the chamber 500 to be filled with liquid. The system 10 may hibernate during the filling of the chamber 500. The sorbent 750 will absorb or adsorb substances from the passing liquid provided that the liquid contains substances that the sorbent 750 is adapted to absorb or adsorb.

(163) The liquid may be rejected from the chamber 500 by resetting the chamber volume 510 to the initial chamber volume 510i by returning the piston crown 420 to the initial position which typically is where the chamber 500 has a minimum chamber volume 512, i.e. where the piston crown 420 is close to the liquid connection 600.

(164) FIG. 10 illustrates a top side view of a system 10 for in-situ accumulation of substances.

(165) The system 10 has a frame arrangement 100 supporting a not shown actuator 20. The actuator 20 is configured for driving the spindle 30. The spindle 30 defines a displacement axis 34 which extends in the same direction as the spindle 30.

(166) The spindle 30 is connected to a flange 300 by a ball screw 32 for reducing slackness.

(167) The flange 300 has a flange periphery 310 defining a shape complementary to a shell 140 being part of the frame arrangement 100 and radially surrounding the spindle 30. The system 10 is disclosed without the shell 140, however the shell 140 must be present for this specific embodiment to work as the system 10 would otherwise collapse.

(168) The flange 300 supports four pistons 400, each piston 400 being connected to the flange 300 by a piston foot 440. The piston foot 440 is secured to the flange 300 using screws. Each piston 400 has a piston shaft 410 extending from the piston foot 440 to the piston crown 420.

(169) The flange periphery 310 further comprises four indents 312 (two are visible) for engaging with four rods 150 (three are visible) longitudinally supported to the not shown shell 140.

(170) Each piston crown 420 are configured to operate in a chamber 500. The piston crowns 420 and chambers 500 define a chamber volume 510 as a function of the displacement of the piston crown 420.

(171) Each chamber 500 has a chamber wing 530 which is used to fixate the chamber 500 to a first and a second chamber plate 110I, 110II by clamping. The chamber plates 110I, 110II are connected to the not shown shell 140, and thereby the chamber 500 is fixated relative to the frame arrangement 100.

(172) Each chamber 500 has a chamber channel 520 adapted for displacement of the piston crown 420.

(173) Each chamber 500 is in a liquid connection 600 with a cartridge 700. The liquid connection 600 has an exhaust 610 with an exhaust valve 620 and a cartridge valve 630 near the cartridge 700.

(174) Each cartridge 700 comprises a cartridge outlet 730 connected to the liquid connection 600, an inlet 710 in direct contact with liquid environment 50 when in intended use. The inlet has inlet wings 720.

(175) Each cartridge 700 has a sorbent 750 (not shown) for accumulation of one or more substances or substance groups.

(176) The cartridges 700 are stabilised by a cartridge plate 120 fixed to the frame arrangement 100 by the (not shown) shell 140.

(177) The system 10 comprises an end plate 200 having a spindle recess 210 for engaging with the spindle 30.

(178) The end plate 200 further comprises a shell recess 230 for engaging with the shell 140 when in intended use. The shell recess 230 forms, in this embodiment, a circular channel.

(179) The system 10 accumulates substances by actuating the spindle 30 causing the flange 300 to be displaced parallel to the displacement axis 34. The piston crowns 420 supported by the flange 300 will likewise displace parallel to the displacement axis 34 away from the frame arrangement 100. This will cause the chamber volume 510 to increase causing a negative pressure in the chamber 500 relative to the liquid environment 50. The negative pressure will drive a liquid volume equal to the change in the chamber volume 510 through the sorbent 750.

(180) The exhaust valve 620 in the exhaust 610 ensures that no liquid enters the chamber 500 through the exhaust 610.

(181) The sorbent 750 will act as a resistance for the liquid passing through and therefore it may take ten minutes for the chamber 500 to be filled with liquid. The system 10 may hibernate during the filling of the chamber 500. The sorbent 750 will absorb or adsorb substances from the passing liquid provided that the liquid contains substances that the sorbent 750 is adapted to absorb or adsorb.

(182) The liquid may be rejected from the chamber 500 by resetting the chamber volume 510 to the initial chamber volume 510i or by returning the piston crown 420 to the initial position which typically is where the chamber 500 has a minimum chamber volume 512, i.e. where the piston crown 420 is close to the liquid connection 600.

(183) FIG. 11 illustrates a system 10 for in-situ accumulation of substances.

(184) The system 10 is identical to the system 10 disclosed in FIG. 10, but the shell 140 with diffusion gaps 142 is shown. The shell 140 is connected to the frame arrangement 100 by clamps 180 and the shell 140 is inserted into the shell recess 230 of the end plate 200.

(185) The space within the shell 140 is filled with liquid from the liquid environment 50 thereby the flange 300 will be exposed to the same pressure on both sides relative to the displacement axis 34 which will increase the precision of the displacement of the flange 300.

(186) FIG. 12 illustrates a spindle 30 with a flange 300 supporting four pistons 400 connected to chambers 500.

(187) FIG. 12A-C discloses the same setup, but in FIG. 12B the setup has a minimum chamber volume 512, and in FIG. 12C the setup has a maximum chamber volume 514.

(188) The spindle 30 defines the displacement axis 34. The flange 300 is connected to the spindle 30 by a screw ball 32.

(189) The flange 300 has a flange periphery 510 with four indents 312 for engaging with not shown rods 150, thereby increasing the stability.

(190) The flange 300 supports four pistons 400 positioned symmetrically relative to the displacement axis 34. Each piston 400 is connected by a piston foot 440 to the flange 300. A piston shaft 410 extends from each piston foot 440 to a piston crown 420.

(191) Each piston crown 420 operates in a chamber 500, thereby defining a chamber volume 510.

(192) Each chamber 500 has a chamber channel 520 adapted for displacement of the piston crown 420 and chamber wing 530 for engaging with one or two (not shown) chamber plates 110.

(193) FIG. 13 illustrates setup of a piston 400, a chamber 500, a liquid connection 600 and a cartridge 700.

(194) The piston 400 comprises a piston shaft 410 extending from piston feet 440 to a distal piston crown 420. The piston crown 420 is configured to cooperate in the chamber 500, thereby defining a chamber volume 510. The chamber 500 having a chamber channel 520 for displacement of the piston crown 420.

The liquid connection 600 comprises an exhaust 610 with a one way exhaust valve 620 and a one way cartridge valve 630 close to the cartridge 700, such that liquid may only enter the chamber 500 through the cartridge 700 and may only exit the chamber 500 through the exhaust 610.

(197) FIG. 14 illustrates a cross section of a shell 140.

(198) The shell 140 is a circular, hollow cylinder. The displacement axis 34 is shown for providing a reference for the placement of the different technical features.

(199) The shell 140 is adapted for the system 10 otherwise disclosed FIG. 10.

(200) The shell 140 has diffusion gaps 142 for diffusion of liquid between the internal parts of the shell 140 or system 10 and the liquid environment. The diffusion gaps 142 have a size, such that the liquid in the system 10 has been replaced between two acts of driving a liquid volume through the sorbent.

(201) The diffusion gaps 142 are positioned near where the cartridge 700 would be placed as the liquid is collected from and around the cartridge 700.

(202) The shell 140 has three cartridge plate channels 170, but only two cartridge plate channels 170 are shown in the cross section of the shell 140. The cartridge plate channels 170 are adapted for receiving and holding a male connection 130 of a cartridge plate 120. An embodiment of the cartridge plate 120 is disclosed in FIG. 17. The cartridge plate channels 170 are configured for allowing the cartridge plate 120 to rotate slightly.

(203) The shell 140 has three first chamber plate channels 160I, although only two are shown in the cross-section.

An embodiment of the second chamber plate 110II is disclosed in FIG. 19.

(205) The first chamber plate channels 160I are slightly offset from the second chamber plate channels 160II relative to the displacement axis 34, such that the first chamber plate 110I and the second chamber plate 110II can fixate one or more chambers 500 to the shell 140 and through the shell 140 to the frame arrangement when in intended use. The chamber plates 110I, 110II fixate the chambers 500 by clamping chamber wings 530.

(206) The chamber channels 160I, 160II have lock arrangements 162 for fixating the male connections 130. The chamber plates 110I, 110II are locked in the lock arrangements 162 by inserting the male connections 140 of the chamber plates 110I, 110II into the chamber channels 160I, 160II and moving the chamber plates 110I, 110II along the chamber channels 160I, 160II to an end. The chamber plates 110I, 110II are then turned, then lifted, then turned again and then moved to an innermost part of the lock arrangements 162. The male connections 130 of the chamber plates 110I, 110II will then be confined.

(207) The shell 140 is equipped with four rods 150 although only two are shown in the cross section.

(208) The rods 150 are adapted for interacting with indents 312 in a periphery 310 of a flange 300 when in intended use. Thereby, the flange 300 moves more stable and precise.

(209) FIG. 15 illustrates end plate 200 in a side view (A) and a top view (B).

(210) The end plate 200 has a spindle recess 210 for receiving and thereby stabilising a spindle 30.

(211) The end plate 200 has a shell recess 230 for receiving a shell 140. In this embodiment the shell recess 230 forms a channel radially surrounding the spindle recess 210.

(212) The shell recess 230 is equipped with four bores 220 for receiving and further stabilising rods 150 otherwise longitudinal supported by the shell 140.

(213) FIG. 16 illustrates an actuator 20 and battery 40 from a top view (A), a side view (B), and bottom view (C).

(214) FIG. 16 discloses how the battery 40 and the actuator 20 are typically arranged when supported by a frame arrangement 100. The battery 40 is connected to a plug 42 for charging of the battery 40.

(215) FIG. 17 illustrates a cartridge plate 120.

(216) The cartridge plate 120 has a substantially circular shape with a centrally positioned cartridge plate spindle bore 124 for a spindle 30 to go through.

(217) The cartridge plate 120 has three male connections 130 for securing the cartridge plate 120 to a shell 140 having a cartridge plate channel 170.

(219) FIG. 18 illustrates a first chamber plate 110I from a top view (A), a bottom view (B), and top side view (C).

(220) The first chamber plate 110I is adapted to be positioned below a second chamber plate 110II, wherein the chamber plates 110I, 110II interact with at least one chamber wing 530 positioned between the chamber plates 110I, 110II.

(221) The first chamber plate 110I has a substantially circular shape with a centrally positioned chamber plate spindle bore 114 for a spindle 30 to go through.

(222) The first chamber plate 110I has three male connections 130 for securing the first chamber plate 110I to a shell 140 having a first chamber plate channel 160I.

(223) The first chamber plate 110I has four chamber plate apertures 112 for fixating up to four chambers 700.

(224) The shape of the four chamber plate apertures 112 is adapted for being inserted into the first chamber plate channel 160I after one or more chambers 500 have been installed in the system 10. Therefore, the chamber plate apertures 112 are adapted for moving past a chamber 500 with chamber wings 530.

(225) Each of the chamber plate apertures 112 has a chamber plate aperture recess 113 extending radially relative to the chamber plate spindle bore 114 for enabling the first chamber plate 110I to be locked in a lock arrangement 162 of the first chamber plate channel 160I by rotation.

(226) FIG. 19 illustrates a second chamber plate 110II from a top view (A), a bottom view (B), and top side view (C).

(227) The second chamber plate 110II is adapted to be positioned above a first chamber plate 110I, wherein the chamber plates 110I, 110II interact with at least one chamber wing 530 positioned between the chamber plates 110I, 110II.

(230) The second chamber plate 110II has four chamber plate apertures 112 for fixating up to four chambers 500.

(231) The shape of the four chamber plate apertures 112 is adapted for being inserted into the second chamber plate channel 160I after one or more chambers 500 and the first chamber plate 110I has been installed in the system 10. Therefore, the chamber plate apertures 112 should only be able to move past part of the chamber 500.

(232) Each of the chamber plate apertures 112 has a shape, which extends radially relative to the chamber plate spindle bore 114 for enabling the second chamber plate 110II to be locked in a lock arrangement 162 of the second chamber plate channel 160II by rotation.
