Passive Sampling Research—Columbia, Missouri. The polar organic chemical integrative sampler (POCIS - on the left) and semipermeable membrane devices (SPMDs - on the right) samplers are used for sampling hydrophilic organic chemicals from water. The SPMDs sampler can also be deployed for air sampling.
