How Can Eurofins TestAmerica Help You?

Eurofins TestAmerica understands the needs of clients undertaking sampling events to identify and monitor emerging contaminants such as PFAS. We have designed a program that leverages our 30 years of experience in LC/MS/MS technology to provide a quality and cost effective solution to your analytical testing needs.

Eurofins TestAmerica offers the nation's largest LCMSMS capacity dedicated to PFAS testing, with over 30 PFAS related compounds at detection limits well below state and federal screening levels. Our laboratories support methods 537.1, ISO25101, 537M and PFAS by QSM  Table B15, with all the necessary validation data to support the precision and accuracy of our methodology. In addition, Eurofins TestAmerica has successfully modified Method 537 for use on more complex matrices, such as groundwater, soil, tissue, and sediment, and has incorporated replacement chemicals such as GenX, DONA and F-53B into this analysis. We also support specialty testing such as PFAS in source air emissions and the production of TOP (Total Oxidizable Precursors) Assay data.

Quality encompasses more than just error-free and defensible data; our industry leading program also incorporates the technical guidance and expertise of our Experts to ensure that we understand your analytical needs and accomplish your data quality objectives.
