S-氰戊菊酯的毛细管气相色谱分析以及氰戊菊酯异构体的分离

Analysis of Esfenvalerate and Separation of Stereoisomer of Fenvalerate By Capillary Gas Chromatograpy

本文采用空心毛细管柱气相色谱法，选用ＯＶ－１为固定液，以癸二酸二异辛酯为内标，在适宜的色谱条件下对５％Ｓ－氰戊菊酯乳油以及氰戊菊酯α、β异构体进行分离和分析。本法对Ｓ－氰戊菊酯的变异系数为０．８２％，回收率１００．４％，线性相关系数０．９９９８。用本法还可以分离氰戊菊酯α、β异构体，且α、β峰高的比值十分稳定，方法的变异系数为０．０９８％，实用、快速、方便。

This paper describes analysis of 5% esfenvalerate EC and separation of stereoisomers of fenvalerate using capillary gas chromatography by OV-1 and di-iso-octyl sebacate as internal standard. The results showed that CV and linear correlation were 0.82% and 0.9998. The average recovery was 100.4%.This method can separate α,β-stereoisomer of fenvalerate completely in tweleve minutes.
