Determination of Fenpropathrin and Dimethoate 20% EC by Gas Chromatography
摘要
Abstract
[Objective] The reference for the quality control and supervision of enterprise and related government office was provided through the research on the isolating and testing method of the fenpropathrin and dimethoate in its 25% EC under same column. [ Method] A specific quantitative analysis method for dimethoate fenpropathrin 25% EC by GC was studied. The sample was separated in a column packed with 5% OV-101 being used as stationary phase and the amyl phthalate as internal standard material. The isolation and the test of the fenpropathrin and dimethoate in its 25% EC were done by flame ionization detector. [ Result] The material including other components could be effectively isolated and tested. The standard deviation for dimethoate and fenpropathrin were 0.049 and 0.045. The coefficients of the variation were 0.30% and 1.07%. The recoveries were in the range from 99.43% to 101.07% and 99.50% to 100. 67%. And the coefficients of linear relation was 0.999 6 and 0.999 8. [Conclusion]This method was convenient, rapid and accuracy,and the testing result was met with the quantitative requirement.关键词
