Device and process for passive sampling

摘要

The present invention generally relates to the field of monitoring or analysing an aqueous system (both water or sediment) for analytes and in particular to processes and devices for sampling and analysing the concentration or levels of specific analytes or solutes in an aqueous system such as a natural water system (e.g., rivers, ponds, etc) or industrial effluent streams. The analytes or solutes may or may not be pollutants of said aqueous systems. The sampling device comprises a polymer inclusion membrane or a composite polymer inclusion membrane.
