PFAS Analysis: Advances, Challenges, and the Road Ahead

Meet the expert panel exploring the analytical challenges of environmental PFAS detection in this LCGC International Peer Exchange®.

The panel unpacks the defining challenge of PFAS analysis: a chemical class so vast and diverse it pushes current methods to their limits.

The panelists debate how to harmonize PFAS methods across a rapidly expanding, poorly standardized universe of compounds.

The panel weighs non-targeted screening against total PFAS measurement to catch the compounds routine targeted methods may miss entirely.

Bryan Vining, David Megson, and Pasquale Avino examine why ultrashort-chain PFAS like TFA are reshaping analytical priorities.

The panel tackles the paradox of background contamination: the lower detection limits go, the more PFAS turn up everywhere.

The experts compare direct injection and solid-phase extraction for handling PFAS in complex matrices.

Asked for one change to ease PFAS analysis, the panel points to better communication and smarter use of AI tools.

The panel closes with a shared message: define your question first, and remember every result is an estimate.
