Per- and Polyfluorinated Alkyl Substances (PFAS) are a group of chemical compounds that have become a focal point of attention and concern within the environmental community and the general public due to their emerging contaminant status. These compounds, with diverse industrial applications and commercial product uses, are pervasive in various consumer goods. Among the product categories where PFAS are commonly found are industrial polymers, stain repellents, waterproofing agents, surfactants, packaging materials, and aqueous film-forming foams (AFFF) utilized in firefighting. These compounds are also extremely chemically stable and persistent pollutants in the environment and food.
Avazyme is one of the first ISO/IEC 17025:2017 laboratories accredited by PJLA, in NC that is specifically accredited for EPA method 1633 (version 4) for 40 PFAS analytes. In addition we offer testing for more than 60 PFAS target analytes in a larger variety of matrices, including food. Avazyme is a member of an AOAC International working group to develop official methods of analysis for PFAS in food. Our combination of PFAS dedicated instruments and expeditious turnaround times, along with experienced, well trained, and proficient personnel allows us to get accurate results quickly to our clients.
