0.5%胺菊酯·苯醚氰菊酯·氯菊酯气雾剂的毛细管气相色谱法分析

Analysis of Tetramethrin+Cyphenothrin + Permethrin in AE Mixture by Capillary Gas Chromatography

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。

A analytical method for tetramethrin cyphenothrin and permethrin in AE mixture by capillary gas chromatography with fused silica column coated with OV-1 was developed. Triphenyl phosphate as internal standard and the FID detector was used. The results showed that the coefficient of variation, average recovery and linear correlation of tetramethrin and cyphenothrin and permethrin were 0.418%, 100.43%, 0.9997% and 0.964%, 99.86%, 0.9997 and 0.494%, 100.03%,0.9998% respectively.
