EPA Method 525.2 Instrumentation Guide

EPA Method 525.2 is a validated analytical protocol developed by the U.S. Environmental Protection Agency for the determination of semivolatile organic compounds (SVOCs) in drinking water. This method uses capillary gas chromatography combined with mass spectrometry (GC-MS), operating in either full-scan or selected ion monitoring (SIM) mode. Laboratories must also employ solid-phase extraction (SPE) for sample preparation. Below are high-performance GC-MS instruments from leading manufacturers that fully meet the analytical requirements of EPA Method 525.2.
