Analysis for PFCs

ESG is experienced in analysis for persistent organic pollutants, including PFCs, such as PFOS and PFOA.

Posing a Risk 

Perfluorinated compounds (PFCs) are a group of man-made chemicals used in products such as coatings on cookware, fabric treatments and firefighting foam.

Aqueous Film Forming Foam (AFFF) used in firefighting contains two types of PFCs, perfluorooctane sulfonic acid (PFOS) and perfluorooctanoic acid (PFOA). 

PFOS and PFOA, which have been used since the 1950s, are Persistent Organic Pollutants (POPs) that persist in the environment, bioaccumulate through the food chain and pose a risk of causing adverse effects to human health and the environment. PFOS is listed in the Stockholm convention on persistent organic pollutants (POPs) and there are proposals to add PFOA.

 

Identification and Quantification of PFCs

ESG offers testing of waters and soils for the identification and quantification of PFOS and PFOA down to parts per trillion (ppt) levels.

Analysis is carried out by LC/MS/MS using stable isotope 13C labelled internal standardisation to compensate for difficult matrix interferences. The use of triple quadrupole mass spectrometry technology allows for high-sensitivity in complex samples.

Furthermore, ESG can supply HDPE containers directly to clients to limit contamination or absorption of PFOS/PFOA from Fluoropolymers (Teflon) and glass containers.
