本文采用内涂OV -1固定液的石英毛细管气相色谱柱和FID检测器 ,以磷酸三苯酯为内标物 ,对胺菊酯、苯醚氰菊酯和氯菊酯三种组分同时进行定量分析。本方法中胺菊酯、苯醚氰菊酯和氯菊酯变异系数分别为0.418%、0.964%和0.494% ,平均回收率为100.43%、99.86%和100.03% ,线性相关系数为0.9997、0.9997和0.9998。
In this paper, OV-1 stationary phase was used for the determination of tetramethrin, cypermethrin and permethrin by using triphenylmethyl phosphate as the internal standard. Quantitative analysis. The coefficients of variation for tetramethrin, cyphenothrin and permethrin were 0.418%, 0.964% and 0.494%, respectively. The average recovery rates were 100.43%, 99.86% and 100.03%. The linear correlation coefficients were 0.9997, 0.9997 and 0.9998.
