目的：建立毛细管气相色谱法测定鱼油中多氯联苯的方法。方法用氢氟酸和浓硫酸的混合溶液消解样品，以正己烷提取、浓硫酸净化后，用毛细管气相色谱法测定。结果方法的回收率为92.6%~105.2%，相对标准偏差(RSD)为2.98%~4.71%，最低检出限为0.25~0.48μg/kg。结论该方法简便、快捷，其灵敏度、准确度和精密度均能满足鱼油中多氯联苯分析的要求。
目的：建立毛細管氣相色譜法測定魚油中多氯聯苯的方法。方法用氫氟痠和濃硫痠的混閤溶液消解樣品，以正己烷提取、濃硫痠淨化後，用毛細管氣相色譜法測定。結果方法的迴收率為92.6%~105.2%，相對標準偏差(RSD)為2.98%~4.71%，最低檢齣限為0.25~0.48μg/kg。結論該方法簡便、快捷，其靈敏度、準確度和精密度均能滿足魚油中多氯聯苯分析的要求。

Objective To establish a method to detect the residual PCBs in fish oil by capillary gas chro-matography. Methods The sample was digested by HF-H2SO4, then extracted by n-hexane and cleaned up by H2SO4, after that determined by capillary gas chromatography. Results The recovery was 92.6%~105.2%, RSD was 2.98%~4.71%(n=5), and the detection limit was 0.25~0.48 μg/kg. Conclusion The method is sim-ple, rapid, sensitive, accurate and precise, it can be used for the determination of polychlorinated biphenyls in fish oil.
