摘要
建立水产品中己烯雌酚的气相色谱-质谱(GC-MS)检测方法。实验样品经乙酸乙酯提取、正相固相萃取小柱净化、进一步衍生后进行GC-MS分析。当添加水平在0.5～1.0μg/kg时,回收率大于75%,相对标准偏差为0.9%～2.7%,线性相关系数为0.999。
The method for determination of diethylstilbestrol (DES) residue in aquatic products by GC-MS was developed. The DES residue was extracted with ethyl acetate and purified with SLH solid-phase extraction (SPE) cartridge. The eluate was evaporated to dryness by N2 at 40 ℃,and DES was then derivitized with bis(trimethylsilyl)trifluoroacetamide (BSTFA)-trimethoxy silane (TMCS) (99:1) in an oven at 80 ℃. The derivate was determined by GC-MS and quantified by comparison with external standards. The recoveries are...
