Presentation Overview

Per-and polyfluoroalkyl substances are a diverse group of synthetic organofluorine compounds widely used in industrial applications and consumer products. PFASs are persistent in the environment, are degradation resistant, and are known to bioaccumulate in humans and wildlife. PFASs have historically been analyzed in drinking water via EPA 537 (14 compounds) and 537.1 (18 compounds). In light of the EPA’s recent announcement on the fifth Unregulated Contaminant Monitoring Rule, which includes 29 PFASs, use of EPA 533 is set to become increasingly important to water testing labs. An updated method, EPA 533, is presented for analysis of multiple short-chain PFASs, including telomers and precursor compounds, that cannot be measured via EPA 537.1. In addition, sources of external contamination in the start to finish analysis of PFASs are reviewed, along with sample processing workarounds to protect the integrity of data generated and achieve desired detection limits.

By watching this presentation you will: 

• achieve a fundamental overview of all existing and up and coming EPA regulated methods for the analysis of PFASs methods
• assess various potential sources of background PFAS contamination within the testing methods and learn what measures can be taken to mitigate those
• learn all start to finish PFAS testing resources UCT offers for this scope of analysis to include SPE consumables, processing manifolds, and analytical columns.
