Low or no disturbance sampling can be accomplished such as through a single-platform aquatic species and habitat sampling system with data integration and rapid processing capabilities that can address the need for sampling at variable depths over varied habitats, along with the simultaneous collection of linked physical and biological data. The platform may be based on a 24-36 foot boat, and may include a net mouth opener brace for an adjustable concentrator net and smaller drift net which may be attached to an adjustable sample chamber, perhaps containing variable mesh capture nets as well as cameras, water sampling equipment, and water quality sensors integrated with a fish finder, GPS, and other monitoring and data recording equipment. The depth of the net mouth opener brace and sample chamber may be adjustable using a depth control.

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.

A fluid sampling device including an inlet configured to receive a portion of a non-homogeneous fluid flowing through a conduit, a first double block bleed valve coupled to the inlet, a first flexible hose coupled to the first double block bleed valve by a first quick acting and leakage free coupling, a collection drum coupled to the first flexible hose by a first control valve, and a container coupled to the connection drum by a manual valve, wherein the device is configured to collect a fluid sample in the container. The device also includes a pressure controller to control pressure within the collection drum, and a level indicator to indicate a level of fluid in the collection drum.

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.

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 method and an apparatus for taking slurry samples from a continuous gravity process flow (PF). The sampling is carried out in two stages by first and second sampling units (1, 2). The primary sample flow (PSF) and the secondary sample flow (SSF) are arranged as pressureless open-channel type flows, so that the flow rate of the secondary sample flow (SSF) to be led for analysis is approximately proportional to an instantaneous flow rate of the process flow (PF). In the apparatus, the first sampling unit (1) and the second sampling unit (2) comprise venting means (23, 24) adjacent the upper ends (25, 26) of their respective first and second side walls (7, 8; 13; 14) to allow equalizing of the atmospheric pressure prevailing inside and outside the first and second sampling units above free liquid levels (27, 28) of the primary and secondary slurry flows (PSF, SSF) along the entire lengths of the sampling units to form pressure—less open-channel type flow paths for the primary and secondary sample flows (PSF, SSF).

A milking system includes a device to sample and analyse a milk sample, including a control unit, a sample supply line connected to the milk line, a pump to control the sample flow, an optical radiation source, and an optical sensor device to detect and analyse optical radiation coming from the reagent pad with said sample, to provide an indication of a substance in the sample, a tape mover to move and unwind the tape from the tape reel, and a pump drive, external to the cassette, and releasably operably connected to the pump device for driving the pump device. The sampling and analysis device also includes a cassette with a sample receiving line, releasably connected to the sample supply line by a liquid connector, and arranged to receive the sample from the sample supply line, a tape reel with a tape that includes a base tape layer and a series of separate reagent pads, and a dosing device to provide a droplet of the sample onto a reagent pad. The dosing device includes a nozzle in fluid connection with the sample receiving line, and a nozzle mover arranged to move the nozzle in at least a longitudinal direction. The cassette is replaceably received in the milking system. Hereby, a large number of parts that are subject to wear and contamination by milk residues are exchanged regularly, which improves measurement reliability and accuracy.

An apparatus includes a body and a fluid sampling conduit disposed within the body. The body is configured to be disposed within a pipe flowing a fluid. The fluid sampling conduit is configured to obtain a sample of the fluid flowing in the pipe. The apparatus includes an odometer wheel coupled to the body and an elastomeric ring surrounding at least a portion of the body. The elastomeric ring is configured to remove material disposed on an inner wall of the pipe as the apparatus travels through the pipe. The apparatus includes a solid sampling subsystem coupled to an external to the body. The solid sampling subsystem includes a capsule, an inlet valve, and a tubing. The inlet valve, when opened, allows at least a portion of the material removed from an inner wall of the pipe to flow through the tubing and into the capsule.
