氰氟草酯及其同系衍生物的分离与测定

Separation and Quantitative Analysis of Cyhaloflp-butyl and Its Derivatives in Cyhaloflpbutyl OD

本文采用高效液相色谱法,以甲醇+水为流动相,使用以2ZORBAX SB-C18为固定相的不锈铜柱和紫外可变波长检测器,在250nm波长下对氰氟草酯及其衍生物进行分离和定量分析。结果表明,该分析方法的氰氟草酯及其衍生物的线性相关系数均为1;标准偏差分别为0.08%和0.05%;变异系数分别为0.74%和0.21%;平均回收率分别为101.1%和99.3%。

A method for separation and quantitative analysis of cyhaloflp-butyl and its derivatives in formulation by HLPC with methanol and distilled water as mobile phase,ZORBAX SBC_(18) column and UV detector at 250 nm wavelength was studied.The result showed that the linear correlations of cyhaloflp-butyl and its derivative were 1,the standard deviations were 0.08%and 0.05%,the variation coefficients were 0.74%and 0.21%,and the average recoveries were101.1%and 99.3%,respectively.
