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,
开发了一种简单快速的气液色谱（GLC）方法，用于分析FMC 33297（间苯氧基苄基顺式、反式-（±）-3-（2,2-二氯乙烯基）-2,2-二甲基环丙烷羧酸酯）的水溶液。该化合物用苯从水溶液中萃取出来，并通过液相色谱进行净化。样品提取物用带有火焰离子化检测器的GLC进行分析，并通过将提取物的积分计数与标准品的积分计数进行比较来定量。FMC 33297的回收率为90%-100%。该方法具有良好的精密度（对0.002394%制剂进行4次测定的标准偏差为6×10^(-6)），对重量百分比为0.00004%的活性成分敏感。
