The soil sample collection container includes first and second ends, the first end of the soil sample collection container being coupled to the second end of the extension member. The collection panel is proximate to the first end of the soil sample collection container, the collection panel moveable to an open position during collection of a soil sample and a closed position during extraction of the soil sample.

The present invention discloses a system for measuring the mechanical properties of sea floor sediments at full ocean depth. The system includes an overwater monitoring unit and an underwater measurement device, where the underwater measurement device includes an observation platform and a measuring mechanism; the observation platform includes a frame-type body and a floating body, a wing panel, a floating ball cabin, a leveling mechanism, a counterweight, and a release mechanism mounted on the frame-type body; the floating ball cabin seals a circuit system; the leveling mechanism adjusts the underwater measurement device horizontally on the sea floor when the frame-type body reaches the sea floor; the release mechanism discards the counterweight for recovery of the unit after the underwater measurement device completes the underwater operation; the measuring mechanism includes at least one of a cone penetration measuring mechanism, a spherical penetration measuring mechanism, and a vane shear measuring mechanism, or a sampling mechanism.

A UAV capable of sampling a hazardous body of water and a method of using the same is disclosed. The method includes receiving, by an electronic controller of the attached apparatus, a first instruction to lower a sampling device at a specified rate into the body of water. The sampling device is connected to the apparatus via a line, and the sampling device is lowered by unspooling the line from a reel. The method also includes lowering the sampling device at the specified rate into the body of water based on the instruction. The method also includes retrieving the sampling device from the body of water. A line-cutting device can cut the line should the sampling device get caught up in an obstruction.

A fluid sample collection system for directly collecting a fluid sample from a fluid source without exposing the fluid sample to an ambient environment that surrounds the fluid sample collection system includes a fluid collector including (i) a sample vial that is configured to retain fluid from the fluid source, the sample vial including a sample vial body and a vial cap that is selectively coupled and sealed to the sample vial body; (ii) a collector body that defines a passenger vial chamber, the sample vial being positioned at least partially within the passenger vial chamber during collection of the fluid; and (iii) a cap access facilitator that is configured to engage a portion of the sample vial to enable a user to selectively couple the vial cap to the sample vial body to seal the sample vial so that the fluid is retained within the sample vial.

A fluid sampling device for sampling fluids in a fluid process vessel through a port in a wall of the vessel, the sampling device comprising a flexible tube with an open end in fluid communication with the fluid process vessel, means to attach the sampling device to the process vessel, wherein at least a portion of the flexible tube is adapted to extend into the process vessel, wherein the length of the flexible tube extending into the process vessel is at least 5 times the outer diameter of the flexible tube.

Methods of passively sampling PFAS in the environment, PFAS sorbents, apparatus and systems (apparatus plus conditions) for sampling groundwater, porewater, and surface water are described.

Disclosed is a method for detection of air-water exchange flux of organic contaminants, which passively and continuously collects contaminants at consecutive points close to a sea surface microlayer, acquires the freely dissolved concentration at the consecutive points of the air and water body close to a water body surface microlayer, and obtains the air-water exchange flux of the contaminants through fitting a self-developed model, wherein the consecutive points include a plurality of sampling points along a height direction above an air-water interface and a plurality of sampling points along a depth direction below the air-water interface. The present invention can be applied to determine the air-water body exchange flux of organic contaminants.

The present disclosure relates to gastrointestinal (GI) tract detection methods, devices and systems.

A testing device for testing the level of a selected chemical in central heating system water in a central heating system circuit comprises: a sample chamber for holding a sample of central heating system water, the sample chamber being connected to the central heating system circuit; means for controlling filling of the sample chamber with central heating system water from the central heating system circuit, and emptying of the sample chamber; at least one valve for isolating the sample of central heating system water from the heating circuit during testing; and optical testing apparatus including a light source and a detector, for measuring an optical property of the sample of central heating system water isolated within the sample chamber and thereby making a determination as to whether or not the level of the selected chemical in the water is greater than a predetermined threshold level.

A Sampler and process for collecting, growing, inoculating and evaluating microbes in-situ. The Sampler may be loaded with an active or inert media to assist with the collection of microbes. It is closed and lowered to a desired depth. Sampler is opened to initiate sampling. Materials are added to the sampler to stimulate growth or change the environment. To collect and grow in situ microbes, the sampler is left open for a period of time, a trigger closes and seals the sampler capturing contents specific to that location. The sampler is lifted preserving the in-situ conditions from the collection location. The contents of the sampler can be interrogated through sealed ports at the field site or at a remote location. The sampler can also be utilized as a biologic reactor allowing researchers to connect laboratory equipment to analyze, modify, or cultivate the collected sample.
