Passive Sampling

Passive sampling set








Passive sampling enables the monitoring of contaminants (micropollutants or biotoxins) in water (surface water, groundwater, coastal water...) for a short (at least 7 days) to long period (with an average field deployment of one month) for which no power, maintenance and supervision is required. An average of the concentration of collected contaminants is measured in the laboratory.



We offer a large range of passive samplers to collect very wide families of natural or synthetic molecules on surface water or on groundwater.

Passive samplers                                               

- The Polar Organic Chemical Integrative Sampler (POCIS) is designed to provide the time weighted average (TWA) concentration of hydrophilic organic chemicals (pesticides, drug residues, EDCs…) during the sampling period. More recently, University of  Bordeaux (EPOC) has also designed a POCIS for the uptake of perfluorinated compounds.

- Passive samplers based on SPE disks are designed to provide TWA concentration of polar or non polar organic compounds as well as metals during the sampling period. 

- Silicone rubbers are the convenient tools for the uptake of non-polar contaminants such as PAHs or PCBs.

- Solid phase adsorption toxin tracking (SPATT) is a new monitoring tool that simulates the biotoxin contamination of filter feeding bivalves.


Advantages of Passive samplers

- Can generate a time-weighted average (TWA) concentration of the contaminants in water

- Deployable in harsh conditions

- No a priori preparation or supervision

- Detection of punctual contaminations

- Higher enrichment of contaminants

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, ....
