文章选用气相色谱外标法分析噻嗪酮、杀扑磷混配制剂,采用Rtx-1色谱柱和FID检测器,对两组分进行同时测定。本方法测定噻嗪酮变异系数为0.39%,平均回收率为99.1%,线性相关系数为0.9984;测定杀扑磷变异系数为1.51%,平均回收率为98.0%,线性相关系数为0.9998。
In this paper, the gas chromatography external standard method was used for the analysis of buprofezin and levofloxacin. The two components were determined simultaneously by Rtx-1 column and FID detector. The method for the determination of buprofezin has a coefficient of variation of 0.39%, an average recovery of 99.1% and a linear correlation coefficient of 0.9984. The coefficient of variation of methiophos was 1.51% with an average recovery of 98.0% and a linear correlation coefficient of 0.9998.
