General Information:

Method 1628 is for determination of all 209 polychlorinated biphenyl (PCBs) congeners in wastewater and other matrices, by low-resolution gas chromatography/mass spectrometry (GC/MS) using selected ion monitoring (SIM). The method calibrates and quantifies 65 PCB congeners selected by EPA as priorities because of their: • chromatographic retention times on the column used for this analysis (e.g., first and last eluting congeners in a level of chlorination),
• prevalence in environmental samples,
• high concentrations in Aroclors, and
• their toxicities (e.g., the World Health Organization’s list of dioxin-like PCB congeners)
