Unravelling the PFAS Puzzle with Comprehensive Targeted and Untargeted Workflows

Learn how different workflows with targeted and non-targeted approaches are used in PFAS analysis

By watching this presentation, you will learn key strategies for:

  • PFAS analysis with targeted and non-targeted LC/MS/MS approaches
  • Workflow development on wastewater with EPA draft method
  • A comprehensive workflow development for PFAS analysis

Event Overview

Per- and polyfluoroalkyl substances (PFAS) pose an increasing threat to the environment, animals, and human beings due to extreme chemical stability and bioaccumulation potential. PFAS analysis is a complex problem that is best addressed with complementary targeted and non-targeted approaches. A comprehensive LC/MS/MS workflow was developed for the PFAS analysis in wastewater based on the existing EPA draft Method 1633 with additional PFAS of varying size and functional groups. Strategies for sensitivity will also be discussed.

However, targeted assays only cover a small fraction of PFAS. Therefore, non-targeted methods and software are very important to understand the health risks of PFAS. Comprehensive software, FluoroMatch suite, covers peak picking, annotation, homologous series detection, assigning confidence, and PFAS data visualization. Workflows taking advantage of the Agilent iterative exclusion approach are shown, as well as data-independent acquisition (DIA) workflows.

These presentations were recorded during ASMS 2023 so if you weren’t able to attend in person here's your chance to watch them on-demand. The presentations are followed by a Q&A.
