摘要:

建立了水产品中己烯雌酚(DES)的超高效液相色谱串联质谱(UPLC-MSMS)检测方法。样品经乙酸乙酯提取后,经正相固相萃取小柱净化,进行UPLC-MSMS分析。当添加水平在0.1~1.0μg/kg时回收率大于75%,相对标准偏差为7.2%~9.2%。

Abstract:

The method for determination of diethylstilbestrol (DES) residues in aquatic products by UPLC-MS/MS was developed. The DES residues were extracted with ethyl acetate, purified with SLH solid phase extraction cartridge, determined by UPLC-MS/MS and quantified by external standard method. When adding diethylstilbestrol to samples in a range of 0.1 to 1.0 μg/kg, the recoveries are above 75%, the relative standard deviations are between 5.5% and 9.2%.

Key words: UPLC-MS/MS, diethylstilbestrol, aquatic products
