Abstract

A method for the determination of six individual chlorobiphenyls in eel-fat, based on saponification of the sample and determination with capillary gas chromatography, was studied collaboratively. Eleven laboratories submitted analytical results in duplo of six individual chlorbiphenyls on two samples naturally contaminated eel-fat. The reproducibility coefficient of variation is about 14% at the 1 mg/kg level per chlorobiphenyl compound and about 23% at the 0.1 mg/kg level. For each compound the mean recovery is about 90% with a standard deviation varying from 7 to 9%.
