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, ….
