Description
Summary:The synthesis and spectroscopic properties of all mono-, di-, tri-, tetra-, penta-, hexa-, and heptachlorobiphenyls are reported. The retention times and molar response factors of all 209 PCB congeners were determined relative to a reference standard, octachloronaphthalene. The retention times were generally found to increase with increasing chlorine content and, for a series of isomers, with increasing meta and para and decreasing ortho substitution. 187 PCB congeners could be separated on a fused silica capillary column coated with SE-54 and only 11 pairs of compounds could not be fully resolved. High resolution isomer-specific PCB analysis is a feasible option for the identification and quantitation of individual PCB in commercial mixtures and environmental samples.
