Abstrakt: This paper gives an account of the systematic, collaborative learning programme undertaken by a group of experienced analytical laboratories within the European Economic Community (EEC) to improve the state-of-the art in the determination of individual chlorobiphenyl congeners in different matrices in preparation for the certification exercises to produce two fish oils as certified reference materials (CRMs). The choice of individual CB congeners, the critical GC parameters necessary to optimise the chromatographic separation and quantification of the congener is given. An assessment is made of the methods of extraction, separation and clean-up of samples prior to gas chromatographic analysis. [ABSTRACT FROM AUTHOR]
