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
