Soils, Sediment, and Other Solids

Eurofins performs analytical services on varied environmental matrices including drinking water, groundwater, soil, sediment, tissue, biosolids, and consumer products using LC/MS/MS and HRMS technologies in support of trace level reporting of emerging contaminants. Within our isolated PFAS laboratory, we run six dedicated systems over two shifts giving us unmatched capacity for any project size. Data can be provided in a Level II, III or IV Data Deliverable format to accommodate unique projects. We follow the EPA protocol to report branched and linear isomers.

Our depth of knowledge, redundancy of systems and state-of-the-art facilities are key to our success in supporting the PFAS market. Eurofins’ reinvestment in the business ensures that we continue to offer highly sensitive methods, low reporting limits and compliance with method protocols meeting regulatory guidance.

TOP analysis is an analytical tool to determine the hidden or unknown mass of PFAS compounds in a sample. Water, soil, sediment and biota are treated with persulfate, hydroxide and heating to create a hydroxyl radical oxidation. This process converts polyfluorinated precursors to the more recalcitrant perfluorinated forms like PFOA and/or PFOS. When the oxidation is complete, the PFAS compounds are extracted and identified employing isotope dilution LC/MS/MS.

AFFF materials treated by the TOP assay have been shown to reveal additional PFAS compounds that can comprise of up to 70% of the fluorinated organics in the sample. The combination of the TOP analysis and the standard suite of PFAS compounds gives a more complete characterization of the PFAS compounds present in the sample.
