Quality control data of fenthion and trifluralin determination in pesticide formulations

Abstract

A “multi-pesticide” method, which makes possible the analysis of a number of active ingredients in formulated pesticides, is presented. Validated analytical methods and Quality Assurance/Quality Control (QA/QC) procedures were adapted for the determination of the active ingredient content of a number of pesticides. The same chromatographic conditions and columns were used for the analysis of trifluralin and fenthion aiming at the further application of the method to as many pesticide formulations as possible, in order to increase laboratory output and reduce the cost of analysis. The method involved gas chromatographic analysis (GLC) using a Flame Ionization Detector (FID). The results presented are statistically evaluated.
