Specifies a method for the determination of polychlorinated biphenyl (PCB) concentration in non-halogenated insulating liquids by high-resolution capillary column gas chromatography using an electron capture detector (ECD). Gives total PCB content; especially useful when a detailed analysis of PCB congeners is necessary. Specifie une methode de determination de la concentration des polychorobiphenyles (PCB) dans les liquides isolant non halogenes, par chromatographie en phase gazeuse sur colonne capillaire a haute resolution utlisant un detecteur a capture delectrons (ECD). Donne la teneur totale en PCB et est particulierement utile quand une analyse detaillee des coneneres des PCB est necessaire.
