Pocis
Polar Organic Chemical Integrative Sampler (POCIS) are passive samplers for water monitoring of a wide range of organic molecules such as Pharmaceutical, Pesticides, Herbicides, Endocrine disruptors, Glyphosate & AMPA, Perfluorinated compounds (PFAS) etc…
Several formats of POCIS are available for natural surface water or for groundwater.

POCIS consists of a solid sorbent contained between two porous membranes. Two metal pieces hold the membranes.
The shape of the pocis depends on the application.
- 90mm rings (with a window of 55mm) is the perfect format for surface water monitoring.
- Mini Passive samplers: a string of three small rectangular POCIS with a width of 4 cm for groundwater monitoring.
- Long passive sampler: a rectangular POCIS with a width of 5 cm and a length of 30 cm for groundwater monitoring.
The sorbent collects the contaminant in water. The organic chemicals are then extracted from the sorbent following a SPE procedure and analyzed using classical analytical methods by HPLC, and LC-MS, ….
- Monitoring of broad range of drugs and pesticides including glyphosate
- Can generate a time-weighted average (TWA) concentration of the contaminants in water
- Formats for surface water monitoring and for groundwater
AFFINISEP provides a complete range of sorbents for the retention of specific molecules or a family of contaminants for Pharmaceuticals, Pesticides, Herbicides, Endocrine disruptors, glyphosate & AMPA, perfluorinated compounds as well as all necessary accessories such as holder, canister, manifold,…

Application note - Passive sampling for the analysis of 12 endocrine disruptors in river water using AttractSPE® POCIS – EDC+
New!
In this application note, AttractSPE® POCIS – EDC+ has been evaluated and calibrated for the uptake of 12 endocrine disruptors before analysis by LC-MSMS. Sampling rates were determined for two stirring speeds.
