Description
Perfluoroalkyl and polyfluoroalkyl substances (PFAS), including PFOA, PFOS, and other persistent fluorinated compounds, are used for their non-stick, water-repellent, and heat-resistant properties in packaging, textiles, cosmetics, fire-fighting foams, and technical coatings. Due to their persistence and potential toxicity, their measurement is essential for verifying regulatory compliance (REACH, POP regulation, FCM), monitoring recycled materials, or controlling environmental contamination levels. Analysis is performed by liquid chromatography-mass spectrometry (LC-MS/MS), allowing the simultaneous detection of numerous PFAS at trace levels in complex matrices: water, extracts, food, polymers, or textiles.
At YesWeLab, we collaborate with a carefully selected network of laboratories, most of which are certified and/or accredited (ISO 17025, COFRAC, etc.). These laboratories are chosen based on your specific needs, the matrices to be analyzed, and the required analytical techniques or methods.
