Advancing PFAS analytics across complex matrices

In this SelectScience® TechTalk, Dr. Stefan Christian Gaugler, Professor of Applied Analytics at the Institute for Chemistry and Bioanalytics, University of Applied Sciences Northwestern Switzerland (FHNW), will provide an up-to-date overview of per- and polyfluoroalkyl substances (PFAS), focusing on their environmental impact, regulatory landscape, and associated analytical challenges. Highlighting the growing concern surrounding PFAS contamination across Europe, alongside the complexity arising from their chemical diversity and persistence.

The session will explore current analytical workflows and sample preparation techniques, including the use of a novel PFAS-selective polymer for micro solid-phase extraction (µSPE), supporting efficient and automated analysis across diverse sample matrices. Attendees will gain insight into approaches for detecting both ultra-short and long-chain PFAS, as well as practical strategies to improve sensitivity, selectivity, and sustainability in PFAS analysis.

What will this webinar cover?

• The environmental relevance and regulatory developments surrounding PFAS in Europe.
• The analytical challenges associated with PFAS diversity, including ultra-short and long-chain compounds.
• Modern analytical workflows for PFAS detection using LC-MS/MS and GC-MS/MS techniques.
• The advantages of novel PFAS-selective polymer-based µSPE methods for efficient and automated sample preparation.
