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, ….
POCIS contains HLB for the monitoring of pharmaceutical drug residues and pesticides.
POCIS for the monitoring of pesticides compounds (For Glyphosate, please use AFFINIMIP POCIS GLYPHOSATE).
