介绍了以OV-101毛细管色谱柱为分析柱,邻苯二甲酸二乙酯为内标物,采用FID检测器对20%霉·稻瘟灵微乳剂中霉灵与稻瘟灵两组分同时进行气相色谱分离测定的方法。结果表明:霉灵与稻瘟灵的线性相关系数分别为0.999 6、0.999 7,标准偏差分别为0.151、0.125,变异系数分别为1.46%、1.22%,回收率分别为98.55%~101.74%、98.50%~100.67%。
This paper introduced OV-101 capillary column as analytical column and diethyl phthalate as internal standard. Simultaneously, FID detector was used for the simultaneous determination of the two components in the 20% Gas chromatographic separation method. The results showed that the linear correlation coefficients of mold spirit and rice blast were 0.999 6 and 0.999 7 respectively, the standard deviations were 0.151 and 0.125 respectively, the coefficients of variation were 1.46% and 1.22% respectively, the recoveries were 98.55% -101.74% and 98.50% respectively % ~ 100.67%.
