POCIS

For the uptake of a wide range of organic molecules including glyphosate and perfluorinated compounds

 

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.

Figure: description of POCIS components

POCIS consists of a solid sorbent contained between two porous membranes. 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, ....

Advantages of POCIS

- 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... as well as all necessary accessories such as holder, canister, manifold, ....

POCIS Kits for groundwater

POCIS is the perfect tools to uptake contaminants in groundwater. Nevertheless an adaptation of the shape is required to go through the narrow diameter of a well. So we have two differents products which can used for a length of around 30cm and a width of about 4-5cm.

for each device, the specific surface is 200 cm2/g.

POCIS Kits containing PRCs

Performance and reference compound (PRC) is a compound not present in the environment (e.g., a deuterated molecule such as DIA-d5), which is spiked in the sorbent phase of the POCIS before its exposure. PRC can be used as internal standards and can correct Rs from varying environmental conditions.Our kit contains 3 cartridges with the same PRC - sorbent as reference for your measurements.
