摘　　要：采用气相色谱法,用DB-1毛细管柱,以邻苯二甲酸二环己酯为内标物,用氢火焰离子化检测器对试样中的环丙唑醇和丙环唑同时进行分离和定量分析。在选定的色谱条件下,有效成分、内标物及未知物能得到有效分离,并能获得较好的检测结果。测得环丙唑醇、丙环唑的线性相关系数为0.9997、0.9999,标准偏差为0.029、0.041,变异系数为0.37%、0.16%,回收率分别为99.38%～100.68%、99.68%～100.52%。A method for separation and quantitative analysis of cyproconazole and propiconazole by GC with DB-1 capillary column, dicyclohexyl phthalate as internal standard and FID detector was described. The result showed that the linear correlation coefficient for cyproconazole and propiconazole were 0.9997 and 0.9999, standard deviation were 0.029 and 0.041, coefficient of variation were 0.37 and 0.16%, the recovery were 99.38-100.68% and 99.68-100.52%, respectively.
