The invention provides a liquid sampler for the automated sampling of liquids at dedicated pre-determined intervals. The liquid sampler includes a liquid inlet connectable to a liquid circuit containing a liquid to be sampled, a sampling reservoir for collecting a liquid sample, and a sampling pump connected to the liquid inlet, operable to extract a discrete amount of liquid from the liquid inlet and to discharge the discrete amount of liquid into the sampling reservoir.

A fluid sensor cartridge that can be used to monitor composition of constituent materials or characteristics of a sample fluid or a patient's blood. The fluid sensor cartridge can be connected in-line with a medical device during a medical treatment. The fluid sensor cartridge can utilize one or more valves, one or more channels, and one or more reservoirs to enable sampling, sensing, and calibrating of a sample fluid or a patient's blood in one container with minimal amounts of sample/blood and calibration fluid.

A titration apparatus includes a titration measuring cell with a titration vessel, a valve device, and a first pump for sucking liquid through a first fluid line into a temporary storage container and transporting it via a second fluid line into the titration vessel. The temporary storage container is arranged in a fluid path between the first pump and the valve device. A third fluid line connects the first pump to the temporary storage container and is filled with a working liquid that does not affect the titration. A second pump conveys a volumetric solution into the titration vessel. An electronic controller controls the first and the second pumps and the valve device to convey a liquid from the first liquid supply into the temporary storage container to transport the liquid into the titration vessel and transport the volumetric solution into the titration vessel to carry out titration.

An autosampler includes a pressure release operation unit for performing, by controlling operation of a needle drive mechanism and a switching mechanism, before a tip end of a needle is pulled out from an injection port following a state where a sampling channel is disposed between a feeding device and an analytical column, a pressure release operation of switching the switching mechanism in such a way that the sampling channel is not disposed between the feeding device and the analytical column and a system including the sampling channel is made an open system, and of performing standby until a pressure inside the sampling channel is returned to atmospheric pressure.

This portable air sampling apparatus includes a Venturi pump creating a vacuum in a suction inlet when compressed air circulates therein; a supply line supplying the Venturi pump with compressed air, including an electrovalve that controls circulation of compressed air in the supply line; a suction line to suction an air sample, having an air circulation member delimiting a chamber for removably receiving a substrate for capturing odorous molecules and suitable for circulating the suctioned air sample through the substrate; and an electronic unit, connected to the electrovalve, controlling its opening and closing so when the electrovalve is opened, compressed air circulates in the supply line through the electrovalve, while when the electrovalve is closed, compressed air circulation in the supply line, between upstream and downstream of the electrovalve, is interrupted by the electrovalve. This enables performing reliable inspections, while being practical and easy to use.

A robot accessory and/or device that provides a sample collector device, a sample storage device, and a work surface. Upon activation, the sample collector device performs a full cycle in which an actuator causes the movement (i.e., extension and then retraction) of an actuator arm that simultaneously causes the top link plate, the lance plunger, the plunger guide, and the plunger to likewise move, including the depression and/or compression and release of the pipette. During this full cycle, this single device is able to remotely collect solid, liquid and/or multiphase samples of potentially hazardous materials and reduces human exposure to this hazardous material and dangerous environment.

An object of the present invention is to provide a dispensing device that can inhibit a dead volume from occurring and can dispense a liquid of a small quantity with a high degree of accuracy while reducing the variation of dispensing quantities. A dispensing device according to the present invention has a detachable dispensing tip and the dispensing tip has a configuration of arranging a plunger in a hollow part of a metal pipe (refer to FIG. 2).

A system and method includes receiving at least one instruction from a first computing system to schedule a test of a fluid. An input device is operated for importing at least a quantity of the fluid from a source. A filling device is instructed for filling a vial with a pre-determined amount of the imported fluid. A drawing device is operated for drawing a pre-determined amount of a reagent. The drawing device is activated for adding the pre-determined amount of the reagent to the vial. An output of a photocolorimeter is read. The output indicates a reaction of the pre-determined amount of the imported fluid and the pre-determined amount of the reagent. A result of the test is transmitted to a second computing system.

A method of sensing hydrocarbons in a subterranean rock formation, including advancing a drilling assembly within the subterranean rock formation. The drilling assembly is configured to discharge a first fluid into the subterranean rock formation, and wherein a second fluid flows past an exterior of the drilling assembly. The method further includes sampling at least one of the first fluid and the second fluid, thereby defining a sampled amount of fluid, and determining a hydrocarbon content of the sampled amount of fluid.

A system may include a needle and source providing fluid to the needle. The system may include a sheath defining an opening. The needle may be within the sheath. The needle and sheath may define a cavity. The system may include a gasket movable between open and closed positions. The gasket may fluidly seal an end of the sheath so that the fluid exits the needle into the cavity and exits via the opening. The system may include a bottle including a septum proximate the end of the sheath. The system may include a movement system that may displace the gasket to permit fluid to exit the cavity via the end of the sheath and displace the sheath or needle such that the needle extends beyond the sheath. The movement system may displace the needle or bottle such that the needle penetrates the septum and fluid exits into the bottle.
