SGS Introduces Ultrashort PFAS Analysis!

We are pleased to offer a sensitive and specific isotope dilution LC-MS/MS method for the measurement of Trifluoroacetic Acid (TFA) and 4 other ultrashort perfluoroalkyl carboxylates and sulfonates. Our method measures these targets at low ng/L from an EPA 1633 extract meaning the same sample can now be used to generate both 1633 data and […]

US DoD and EPA Update on PFAS Methods

The annual DoD EMDQ Workshop, usually a source of great information and networking, was cancelled this year. To cover updates that would have been discussed at the workshop, the DoD team hosted an informative webinar on multiple topics. Highlighted below are some PFAS methods updates from Janice Willey’s May 19 presentation. The PFAS Isotope Dilution […]

Extracting Cationic and Zwitterionic PFAS from AFFF-Contaminated Soils

The PFAS on the regulatory radar, such as PFOS, PFOA, and other related targets on typical laboratory lists, are anionic, or neutral. Therefore, the methods are optimized for anionic PFAS and feature standardized solid extraction using methanol containing ammonia, and weak anion exchange cleanup. However, many aqueous film forming foam (AFFF) active ingredients can be […]

How does PFAS contamination affect microbial communities?

The widespread use of aqueous film forming foams (AFFF) containing PFAS at airports all over the world has resulted in contamination of ground and surface water, and soil. In addition to the many ecosystem effects that are still being studied, how are microbial communities affected? Which PFAS are microbes able to degrade and how does […]
