在同一色谱柱上,采用程序升温的气相色谱方法对20%水胺.氯氰菊酯乳油中有效组分进行分析研究:采用5%OV-3/101硅烷化白色担体为填充物的不锈钢柱和氢火焰离子化检测器,以癸二酸二正丁酯为内标物,三氯甲烷作溶剂,测出水胺硫磷、内标物和氯氰菊酯的保留时间分别为2.2min,4.3min,7.2min。研究表明,水胺硫磷和氯氰菊酯的标准偏差分别为0.18和0.013,变异系数分别为0.95%和0.83%,平均回收率分别为99.91%和99.25%,线性相关系数分别为0.99978和0.99985。
On the same chromatographic column, the active components of 20% aqueous amine-cypermethrin EC were analyzed by gas chromatography with temperature-programmed rise: stainless steel column packed with 5% OV-3/101 silanized white support and hydrogen flame Ionization detector, sebacic acid di-n-butyl ester as internal standard, chloroform as solvent, measuring the water amine parathion, internal standard and cypermethrin retention time were 2.2min, 4.3min, 7.2min. The results showed that the standard deviations of isocarbophos and cypermethrin were 0.18 and 0.013, respectively. The coefficients of variation were 0.95% and 0.83% respectively. The average recoveries were 99.91% and 99.25% respectively. The linear correlation coefficients were 0.99978 and 0.99985 respectively.
