The Polar Organic Chemical Integrative
Sampler (POCIS) is designed to provide the time weighted average (TWA)
concentration of hydrophilic organic chemicals (pesticides, drug residues,
Glyphosate & AMPA, EDCs…) during the sampling period. POCIS can be supplied
with or without Performance Reference Compound (PRC). Historically developed
for polar compounds, some applications have been developped for non polar
compounds such as Perfluorinated compounds (PFAS) thanks to the right
combination of sorbent/membranes.

Silicone rubbers are the
convenient tools for the uptake of non-polar contaminants such as PAHs or PCBs.
o
Solid phase adsorption toxin tracking (SPATT) is a new
monitoring tool that simulates the biotoxin contamination of filter feeding
bivalves.
AFFINISEP
provides a complete range of sorbents for the retention
of specific molecules or a family of contaminant for Pharmaceutical,
Pesticides, Herbicides, Endocrine disruptors, perfluorinated compounds,
Biotoxins, metals… as well as all necessary accessories such as holder,
canister, manifold, ….
Some passive
samplers such as disks passive samplers and POCIS can uptake similar compounds
depending on the good choice of the sorbent/membrane.
