LC-MC测定饲料中己烯雌酚方法的研究

Study on the Determination of Diethylstil Bestrol in Feed by LC-MS

建立了LC MS测定饲料中己烯雌酚的分析方法 ,最低检出限 0 .5ng ,回收率平均 92 .86 % ,平均变异系数5 .6 4 % 。

An analytic method of determining diethylstilbestrol in feed by LC MS has been studied systematically.The detecting limit of the method for DES is 0.5ng, CV is 5.64%,RC is 87.20%～94.14%.The method has been applied to the analysis of any kinds of feed of animals.
