EPA Method 8280 B Instrumentation Guide

EPA Method 8280 B is a U.S. EPA-approved analytical method designed for the determination of polychlorinated dibenzo-p-dioxins (PCDDs) and polychlorinated dibenzofurans (PCDFs) in environmental samples. These toxic compounds are often found in soil, sludge, fly ash, sediments, and chemical waste. The method requires the use of High-Resolution Gas Chromatography (HRGC) paired with Low-Resolution Mass Spectrometry (LRMS), operated in Selected Ion Monitoring (SIM) mode to accurately identify and quantify specific toxic congeners, especially those with 2,3,7,8-substitution patterns.
