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.

Glyphosate
Ready-to-use kits for the analysis of Glyphosate from a variety of samples matrices: water (surface, river, underground, geothermal), cereals, urine, honey, tea, …
Estrogens
Ready-to-use kits for the analysis of synthetic or natural estrogens from water or biological samples.
Phenolics
Ready-to-use kits for the analysis of Phenolic compounds from a variety samples, such as in water, cosmectics products, biological or food matrices like meat.
Passive Samplers for groundwater
Passive sampling in groundwater requires change of the shape of these tools due to their introduction in narrow wells.
These passive samplers are available for POCIS or disks passive samplers for the determination of organic molecules such as Pharmaceutical, Pesticides, Herbicides, Endocrine disruptors, Glyphosate & AMPA, Perfluorinated compounds (PFAS)
Silicon rubber
A very powerful tool for the monitoring of non-polar contaminants such as PAHs, PCBs or hydrophobic pesticides.
Different shapes available
Accessories
Several accessories are required for the use of passive samplers on the field, hold them and to protect them.
