Abstract

The illicit contamination of used mineral oils with chlorobiphenyls (CBs) continues to be a serious problem, and these waste materials need to be monitored regularly to determine the level of CBs which may have been added. A certified reference material containing a known level of CBs in mineral oil is an essential aid to the quality control of this analysis. In previous exercises the Community Bureau of Reference certified CBs in two fish oils and in a sewage sludge. In this paper details of the preparation, stability and homogeneity of a mineral oil are given. The method of sample preparation, clean-up, instrument calibration, chromatographic separation, compound identification and quantification is described. The results of the intercomparison exercise are presented, and the data and main sources of error are assessed.
