Abstract: | A new method for determination of the organochlorine,pyrethroid pesticide residues in agricultural products. was developed through installation of dual ECD detector gas chromatography,single-tower double column dual detector. This method did not have to shut down to change the column for two column qualitative and quantitative analysis. The method could save a large number of qualitative analysis for chlorothalonil,cyfluthrin,triazolam tong,cypermethrin spiked recovery experiments. The average recovery of this method was 95.0% and 102.5%,relative standard deviation was 1.88% ~ 3.72%,showing this method is stable and reliable. |
