SEMIPERMEABLE MEMBRANE-BASED SAMPLING SYSTEMS

摘要

The device and methods relate to a sampling device (2) for obtaining samples of analytes in a difficult-to-reach sampling location, such as below ground or underwater, and transporting the sample to an accessible delivery or collection site. The sampling device (2) comprises a semipermeable membrane-based sampling chamber (28), which can be positioned under the ground or water surface where analytes of interest can permeate into the chamber into the semipermeable membrane-based sampling chamber (28). Transfer channels (21, 22), which communicate with the semipermeable membrane-based sampling chamber (28), is used to transport the sample to the surface for analysis without removing the semipermeable membrane-based sampling chamber (28) from the sampling location.
