A method for determination of 6 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 duplicate for 6 individual chlorobiphenyls on 2 naturally contaminated eel fat samples. The reproducibility coefficient of variation was about 14% at the 1 mg/kg level for each chlorobiphenyl compound and about 23% at the 0.1 mg/kg level. For each compound, the mean recovery was about 90% with a standard deviation varying from 7 to 9%.
协同研究了一种基于样品皂化及毛细管气相色谱法测定鳗鱼脂肪中6种单个氯代联苯的方法。11个实验室对2份天然受污染的鳗鱼脂肪样品中的6种单个氯代联苯进行了双份分析并提交了结果。每种氯代联苯化合物在1 mg/kg水平下的重现性变异系数约为14%，在0.1 mg/kg水平下约为23%。对于每种化合物，平均回收率约为90%，标准偏差在7%至9%之间。
