Extraction of 40 PFAS Compounds from Soil and Tissue Following EPA Method 1633A
PFAS “forever chemicals” continue to accumulate in soil and tissue, driving the need for faster, more reliable environmental testing. This study demonstrates how automated extraction following EPA Method 1633A enables efficient analysis of 40 PFAS compounds from complex sample types. Using the EDGE PFAS system, extractions were completed in under 15 minutes per sample with strong recoveries and no carryover. The approach supports high-throughput workflows while maintaining accuracy and consistency in PFAS monitoring.
