A milking system includes a milking device, a milk line for carrying milk from the milking device, and a sampling unit that is arranged to take a sample from the milk line and to test the sample for the presence or concentration of at least one substance. The sampling unit is provided with a control unit and a housing. The housing includes therein a supply reel with a tape that carries reagent, and a sample supplier to supply, under control of the control unit, a part of the sample to the reagent on the tape. The sampling unit further includes a tape displacer displacing the tape under control of the control unit, a sample analyser, and a used tape collector device collecting tape with reagent to which a sample has been supplied. The supply reel at a surface thereof includes a desiccant, or is completely made of a desiccant material. This provides such a large volume of desiccant that the correspondingly high moisture absorption capacity ensures along uninterrupted useful life of the sampling unit, and thus of the milking system.

A water quality sampler includes a membrane receptacle and at least 7 sample membranes. The membrane receptacle comprises at least 7 membrane cavities disposed on a top surface of the membrane receptacle. Each membrane cavity is configured to hold a sample membrane and the sample membranes are each removably positioned within the membrane cavities and extend at least 1 cm out from the top surface of the membrane receptacle. A bottom of the membrane receptacle comprises a protruding lip that traces a bottom edge of the membrane receptacle in a downward direction, where the protruding lip encompasses a stacking chamber capable of receiving a top end of a second water quality sampler to allow stacking of multiple water quality samplers.

A cryogenic liquid sampling system including a chamber having affixed therein a sample pump to proportionally pull a cryogenic liquid sample from an external source to a constant pressure piston accumulator and an enclosure. The enclosure includes a supply port to receive an input stream of a gas, an input port connected to the chamber via a vacuum line, a sample pump port connected to the chamber via a pump line and configured to feed therethrough gas received at the supply port to the sample pump, a vacuum device connected to the input port and configured to generate a vacuum within the chamber by pulling air from the vacuum line, and processing circuitry to control the vacuum device and the sample pump to perform transfer of a cryogenic liquid sample from the external source to an external device.

The disclosure provides a method for sampling groundwater. The method includes extracting groundwater from a monitoring well in a first flow rate; monitoring groundwater level in real-time, and calculating a decrease of the groundwater level during the extracting in the first flow rate based on the real-time monitored groundwater level; when the decrease of the groundwater level is equal to a first value, extracting groundwater from the monitoring well in a second flow rate, the second flow rate being smaller than the first flow rate; and when the groundwater level is in an equilibration state, extracting groundwater from the monitoring well and using the extracted groundwater at this time as a representative groundwater.

A milking system includes a milking device, a milk line, and a sampling and analysis device for the milk that includes a control unit, a tape mover to move and unwind a tape wound on a tape reel and with a base material with reagent pads, that detect a substance in the sample, and a dosing device to provide the sample onto a reagent pad, and a sensor to detect radiation from said reagent pad, and to analyse the detected radiation to indicate a presence or concentration of said substance. The reagent pad is facing downward during provision of the sample. In this way, the chance of excess liquid falling from the reagent, and possibly onto a camera, is reduced. Smaller reagent pads may be used, it reduces the chance of supplied liquid spilling over to a neighbouring reagent pad, the measures preventing this spilling may be limited, and it is easier to suck away excess fluid.

A system and method for sampling of liquid products. The system includes a portable, releaseably connected product sample receiving assembly and a plurality of product sampling and mixing assemblies. The product sample receiving assembly can be attached and detached from two or more the product sampling and mixing assemblies, so that a single product sample receiving assembly can be used to service multiple product sampling and mixing assembly locations at different times. Each of the multiple product sampling and mixing assemblies includes a suction assembly and a discharge assembly on opposite sides of a static mixer. The product sample receiving assembly may include a slip-stream configuration or in-line configuration. The product sampling and mixing assemblies may be unidirectional or bidirectional.

Apparatus and installation methods for sampling ports are disclosed. Sampling ports include a port housing and a lid assembly. The lid assembly is configured to sealably close against the port housing. Additionally, the lid assembly can be secured, such as with a lock, to the port housing. In one aspect, the port housing includes a sample mount arrangement configured to receive a sampling assembly. The sample mount arrangement defines a sampling channel and the port housing defines a sampling opening and a first securing mount. The lid assembly includes a latch arrangement and defines a second securing mount.

An apparatus for obtaining samples from a process, and which can be located in the process, which comprises a gate which reciprocates between a first position and a second position to fill and empty a sample chamber via corresponding inlets and outlets. The gate may pivot within the chamber about a longitudinal axis through the chamber, and a dam prevents fluid flow directly between the inlets and outlets. The inlets may provide outlets, and vice versa, depending on the direction of movement of the gate. Means such as pumps may be provided to agitate the fluid samples obtained by the apparatus, and sensors mounted in the sample chamber (for example on the gate or on the dam) can perform measurements on the samples. Wipers may be provided on the gate to assist in the ingress and egress of samples into and out of the sample chamber. It is also possible to inoculate the fluid samples within the sample chamber.

A passive sampling device is provided that is comprised of a member having a first surface and a second surface opposite the first surface and a hole through the member extending from the first surface to the second surface. An adsorbent material is positioned between two mesh members. The adsorbent material allows for efficient and selective removal of organic molecules, such as, for example, perfluoroalkyl substances.
