PFAS water analysis: From workflow selection to broader screening

PFAS analysis is placing increasing demands on laboratories. Evolving regulations, lower detection limits, growing sample volumes and complex matrices all make selecting the right analytical approach more important than ever.

Velaris PFAS Water Automated Workflow

To support laboratories facing these challenges, Velaris has brought together expertise, workflows and analytical solutions from Skalar, GERSTEL, TRACE, LCTech and PromoChrom. The Velaris PFAS Water Resource Page provides a central overview of automated solutions for solid-phase extraction (SPE), extractable organic fluorine (EOF) and adsorbable organic fluorine (AOF), supporting PFAS analysis across drinking water, surface water, groundwater, wastewater, sludge and other aqueous matrices.

For laboratories working in industrial, energy and environmental testing, broader screening methods can provide valuable information beyond targeted compound lists. EOF and AOF are method-defined parameters that help assess organic fluorine in water samples and can indicate the presence of unknown or emerging fluorinated compounds. Combined with automated sample preparation and Combustion Ion Chromatography, these approaches can support efficient first-line screening and help prioritise samples for more detailed targeted analysis.

PFAS Water Compliance Guide

Laboratories can also access the PFAS Water Compliance Guide, a practical eBook developed to support informed workflow decisions. It brings together guidance on regulatory expectations, analytical standards and matrix-specific challenges, with practical considerations for selecting and implementing SPE, EOF and AOF workflows. 

Register for the Velaris PFAS Water Webinar

The upcoming Velaris webinar, “PFAS Screening in Aqueous Matrices by EOF and AOF Analyses,” will take place on Tuesday, 25 August 2026 at 2:00 PM CEST. Presented by Larissa Ram, Product Manager at TRACE, the session will explain the principles of EOF and AOF analysis, the full AOF sample-preparation workflow and the role of automated Combustion Ion Chromatography in trace-level fluorine determination. It will also show how these screening methods can complement targeted LC-MS/MS analysis.
