摘　　要：在文章中,建立了液相色谱法同柱分析24%霜脲氰·氰霜唑悬浮剂的含量的分析方法,以乙腈和水为流动相,使用Kromasil C18/5μm为填充料的不锈钢柱,检测波长为215nm。结果表明,在该方法中霜脲氰、氰霜唑的标准曲线线性相关系数分别为0.999975和0.99975,标准偏差分别为0.069和0.036,变异系数分别为0.42%和0.44%,平均回收率分别为99.90%和100.17%。In this paper,an analytic method for the determination of the two active ingredients in Cymoxanil+Cyazofamid 24%SC was established by using liquid chromatography with a Kromasil C18/5μm column,acetonitrile and water as mobile phase and DVD detector at 215nm.The results showed that the linear regression coefficients of 0.999975 and 0.99975,the standard deviation of 0.069 and 0.036,the variation coefficient of 0.42%and 0.44%,and the average recovery of 99.90%and 100.17%were obtained for Cymoxanil and Cyazofamid,respectively.
