  • REPORT ON THE IMPROVEMENTS IN THE DETERMINATION OF CHLOROBIPHENYLS LEADING TO THE CERTIFICATION OF SEVEN CBS IN TWO FISH OILS AND IN SEWAGE SLUDGE

Abstract

This report gives an account of the systematic, collaborative learning programme undertaken by a group of experienced analytical laboratories within the EEC to improve the state-of-the art in the determination of individual chlorobiphenyl congeners in different matrices. The improvements were incorporated into analytical methods which were used in the subsequent certification exercises to produce two fish oils as Certified Reference Materials (CRMs). The report gives details of the choice of individual CB congeners and the critical GC parameters necessary to optimise and maintain the desired chromatographic separation and quantification of each congener. An assessment is made of the methods of extraction, separation and clean-up of samples prior to gas chromatographic analysis.
