Comprehensive global PFAS testing with advanced analytical technologies

Eurofins Environment Testing offers extensive analytical services for diverse environmental matrices including drinking water, groundwater, soil, sediment, tissue, biosolids, and consumer products. Utilising advanced technologies such as LC/MS/MS and high-resolution mass spectrometry (HRMS), Eurofins Environment Testing provides trace-level detection of emerging contaminants worldwide. Our dedicated PFAS laboratories operate multiple specialised instruments across shifts, delivering unmatched capacity to accommodate projects of any size.

Eurofins Environment Testing laboratories provide data in flexible formats tailored to meet unique project requirements and adhere to international protocols for reporting branched and linear isomers of PFAS.

Expertise, contingency instrumentation, and cutting-edge facilities ensure the highest sensitivity, low reporting limits, and strict compliance with regulatory guidance globally.

Total Oxidizable Precursor (TOP) Analysis

The TOP assay is a powerful technique used to identify the hidden or unknown fraction of PFAS compounds in environmental samples. By treating water, soil, sediment, and biota with persulfate, hydroxide, and heat to induce hydroxyl radical oxidation, polyfluorinated precursors are converted into more persistent perfluorinated forms such as PFOA and PFOS. After oxidation, PFAS compounds are extracted and quantified using isotope dilution LC/MS/MS.

Testing of Aqueous Film Forming Foam (AFFF) materials with the TOP assay often reveals additional PFAS species that may account for up to 70% of the total fluorinated organics present. Combining TOP analysis with standard PFAS screening provides a more complete and accurate characterisation of PFAS contamination in samples.
