EPA Method 508.1 Instrumentation Guide

EPA Method 508.1 is a validated analytical protocol used to detect chlorinated pesticides and herbicides in drinking water. This method employs gas chromatography with electron capture detection (GC-ECD) for its high sensitivity to halogenated compounds. To comply with regulatory standards, laboratories must use robust and accurate GC systems with exceptional detection limits. Below, we highlight top GC-ECD systems from leading manufacturers, offering the performance and reliability necessary for precise pesticide quantification in drinking water analysis.
