A quantitative analysis method was established for metalaxyl + hymexazol 3% aqueous solution by gas chromatography in this paper. The results showed that the linear correlations for hymexazol and metalaxyl were 0.999 2 and 0.9998, the standard deviations were 0.041 and 0.012, the coefficients of variation were 1.63% and 2.31%, the average recoveries were 99.5% and 99.7%, respectively.%采用气相色谱法对3％甲霜·(噁)霉灵水剂中的(噁)霉灵和甲霜灵进行同柱一次性分析和定量.结果表明,该方法中(噁)霉灵和甲霜灵的线性相关系数分别为0.9992和0.9998,标准偏差分别为0.041和0.012,变异系数分别为1.63％和2.31％,平均回收率分别为99.5％和99.7％.
