Presentation 1: Hydrolysis as a Critically Important Step in the Analysis of Fluorotelomer Alcohols in Textiles and Other Products
by Vladimir Nikiforov, Senior Scientist, Environmental Chemistry and Health Effects, NILU, Tromsø
In this presentation, a simple hydrolysis-based approach for identifying and accounting for PFAS precursors in consumer products and environmental samples is presented by its creator. The theory behind the method is explained. Advantages and limitations of the recently certified EN 17681-1:2025 method are discussed. Hydrolysis is compared to oxidation as an alternative/complementary work-up for release of perfluoroalkyl substances.
The presentation focuses on fluorotelomer alcohol (FTOH)-based precursor compounds, including polymeric materials that may degrade into regulated or hazardous PFAS. Watch to learn how a straightforward hydrolysis procedure can convert precursor compounds into detectable free FTOHs while preserving valuable structural information for source identification and risk assessment. Case studies from textile extracts demonstrate how preliminary hydrolysis revealed up to 1300-fold higher levels of previously “hidden” FTOHs compared to conventional analysis alone.
Presentation 2: PFAS Analysis in Animal‑Derived Foods Using a Direct Blend & Inject LC‑MS/MS Workflow
by Phil Taylor, Marketing Lead – Food & Environmental, PerkinElmer
Per‑ and polyfluoroalkyl substances (PFAS) present major analytical challenges in animal‑derived foods due to complex matrices and tightening regulations. This presentation demonstrates a direct Blend & Inject LC‑MS/MS workflow for quantifying 25 PFAS compounds aligned with EPA Method 533 and EU requirements. The approach delivers ppt‑level sensitivity, excellent linearity, and robust performance without solid‑phase extraction.
Presentation 3: PFAS in Food – Addressing Contamination in the Food Supply Chain
by Margot Lee, Senior Scientist, Waters Corporation and MJ Madden, Technical Support Manager and Project Manager, PromoChrom Technologies
PFAS contamination in food presents a growing analytical and regulatory challenge, particularly as attention expands beyond water into complex food and animal protein matrices. In this session, Waters and PromoChrom experts explore practical, mostly automated workflows designed to improve robustness, efficiency, and data quality in PFAS food testing.
The presentation features real-world examples of PFAS analysis in food matrices, including eggs and animal proteins, highlighting different sample preparation strategies adapted to matrix complexity and laboratory throughput needs. Watch and gain insight into how pressurized solvent extraction, SPE cleanup, and QuEChERS-based approaches can be combined with automation to streamline workflows while maintaining sensitivity and reproducibility.
As PFAS testing in food continues to evolve, this session also provides a forward-looking view on emerging workflow optimizations and how labs can prepare for expanding regulations and increasing analytical demands.
