Dr. Katinka Ruth, Senior Application Specialist IC, and Theresa Steurer, Product Specialist IC at Metrohm International Headquarters discuss how laboratories can make sure that their analyses capture all PFAS compounds. They present combustion ion chromatography (CIC) and ion chromatography coupled with mass spectrometry (IC-MS/MS) as reliable techniques for PFAS analysis.
CIC and IC-MS/MS for PFAS analysis
Per- and polyfluoroalkyl substances (PFAS) comprise a group of highly persistent compounds that pose significant environmental concerns, particularly in water quality monitoring. Comprehensive characterization of PFAS contamination remains analytically challenging due to the chemical diversity of these substances and the limitations of individual methods. This webinar presents two complementary techniques that provide a comprehensive picture of PFAS levels.
Key learnings of this webinar:
- Understand the regulatory background for PFAS analysis in water (DIN 38409‑59, ISO 18127, EPA 1621, DIN 38407‑53)
- Learn how combustion ion chromatography (CIC) enables the reliable determination of total PFAS-related parameters such as AOF
- Understand the relevance of trifluoroacetic acid (TFA) as a key ultra-short chain PFAS in water quality monitoring
- Discover how IC‑MS/MS provides a sensitive and reliable approach for TFA determination according to DIN 38407‑53
