Popis:	The structure-sensitivity relationship of polybrominated biphenyls analyzed by an electron-capture detector was investigated. The greates variations i n sensitivity with positional isomerism occurred for the least brominated isomers and for polybrominated biphenyls with bromine substituents on only one ring. The ratio of sensitivity (on a molar basis) of decabromobiphenyl to 2-bromobiphenyl was ca. 50, with response increasing approximately linearly with degreed of bromination. Increased detector temperature resulted in improved sensitivity. The presence of oxygen in the carrier gas resulted in slightly decreased sensitivity.
