Abstract:A gas chromatography method was established to determine dichlorvos and cypermethrin in the mixture formulation emusifiable concentrate(EC). The gas chromatography method was acquired with weak polar column and programmed temperature, dichlorvos and cypermethrin content in the formulation were detected under the conditions such as FID detector and double interior standard quantitation. The results showed that the linear correlation coefficients for dichlorvos and cypermethrin were 1.000 0 and 0.999 95,the RSD 1.96% and 0.85%, and average recovery were 99.23% and 99.51%, respectively. Indicating that the method was satisfactory for analysis of dichlorvos and cypermethrin content in the formulation.
