Lu Yanfen Huang Chaoqun(Hunan Research Institude of Chemical Industry,Changsha 410007)
A quantitative analysis method was established for dichlorvos-cypermethrin EC by gas chromatography with 5% OV-101 fcolumn. The results indicate that the variation coefficient and recovery were 1.92%, 99.9%～101.7% and 1.68%, 98.4%～100.4% for dichlorvos and cypermethrin respectively. The method has been used in production with satisfactory results.
