| Abstract: | A simple and rapid gas-liquid chromatographic (GLC) method was developed for the analysis of aqueous solutions of FMC 33297 (mphenoxybenzyl cis,trans-(+/-)-3-(2,2-dichlorovinyl) - 2,2 - dimethylcyclopropanecarboxylate). The compound is extracted from aqueous solution with benzene and cleaned up by liquid chromatography. The sample extracts are analyzed by GLC with a flame ionization detector and quantitated by comparing integrator counts of extracts with those of standards. Recoveries of FMC 33297 were 90-100%. The method has good precision (the standard deviation for 4 determinations of a 0.002394% formulation was 6 X 10(-6)) and is sensitive to 0.00004% active ingredient by weight, |
