Polar Organic Chemical Integrative Sampler (POCIS) are very common and useful passive samplers for monitoring polar organic chemicals in several aquatic environments such as freshwater, groundwater, seawater, etc…

This Integrative sampling method can adsorb an extensive range of contaminants such as pharmaceuticals and personal care products (PPCPs), pesticides including glyphosate, endocrine disruptors, fragrances, fire retardants, perfluorinated compounds, plasticizers, and their degradation products.

Initially, POCIS was designed to mimic the respiratory exposure of aquatic organisms to dissolved chemicals. Nowadays they are used either as qualitative tools to determine contaminants present in the environment or as quantitative tools to determine the Time Water Average Concentrations (TWACs). This requires more information and is influenced by environmental parameters.

POCIS are very popular because they are easy to use and require no maintenance and energy during the exposure period.

Several formats are available to adapt sampling to field constraints.
The most popular product is the round POCIS (90mm diameter). However, two other narrow formats (5 cm width) are also available for groundwater monitoring.

Affinisep has selected several combinations of sorbent and membranes to efficiently monitor a broad range of contaminants:

POCIS with a PRC

In addition, AttractSPE®POCIS HLB and AttractSPE®POCIS pesticides can be supplied with a performance reference compounds (PRC). The dissipation of the PRC during the exposure period can be used to correct the evaluated concentration. For these POCIS, desisopropyl-atrazine-d5  (DIA-d5) can be used as PRC.
