Polar Organic Chemical Integrative Sampler (POCIS)
What are POCIS?
See image above – right hand side canister
- POCIS sequesters primarily hydrophilic/polar type substances. Substances with a log Kow< 4
- Each POCIS disk consists of a microporous polyethersulfone membrane encasing various solid phase sorbents or mixtures of sorbents
- Different sorbents can be used for different classes of pollutants
- The POCIS holder housed within the NLS passive sampler accommodates three disks
