百·甲混剂的气相色谱分析

Analysis of the Mixture of Chorothalonil and Metalaxyl by GC

摘要:

采用气相色谱法,以邻苯二甲酸二丁酯为内标物,在SE-30毛细石英玻璃柱上进行分离测定。方法的标准偏差0.49,0.42。该方法对两种有效成分测定的变异系数分别为0.46%和0.53%,回收率分别为98.96%～100.25%和99.23%～100.18%。

Abstract:

A method was analysised by GC on SE-30 Capillary column.Di-n-buyl phthalase was used as the internal standard.The standard deviation, coefficient of variation and recovery were 0.49, 0.42, 0.46%, 0.53%, 99.46%～100.25%, 99.23%～100.18%.
