The Environmental Protection Agency (EPA) has released method 8082 for the analysis of PCBs as Aroclors, having tested the method against a select group of 19 congeners common to many Aroclor mixtures. The analysis of Aroclors and PCBs is complicated by matrix effects and the method allows the analysis of Aroclors, using those selected congeners, and also enables the analysis of other PCBs if appropriate quality controls are in place.
