以5%OV-101色谱柱为固定相,邻苯二甲酸正戊酯为内标物,利用FID检测器通过程序升温方法对20%唑酮.三环唑可湿性粉剂中三唑酮和三环唑进行气相色谱分离和测定.结果表明:唑酮.三环唑20%可湿性粉剂中三唑酮和三环唑及杂质得到了有效分离,三唑酮和三环唑的标准偏差分别为0.075和0.093,变异系数分别为0.71%和0.91%,回收率分别为99.48%～101.26%和99.43%～100.63%,线性相关系数分别为0.9998和0.9996. Using 5% OV-101 as stationary phase and n-pentyl phthalate as internal standard, the toxicity of triadimefon and tris Cyclotriazole was separated and determined by gas chromatography.The results showed that triadimefon and tricyclazole and impurities in 20% WP of tricyclazole were effectively separated, and the standard deviations of triadimefon and tricyclazole were 0.075 and 0.093 respectively. The coefficients of variation were 0.71% and 0.91%, respectively. The recoveries were 99.48% -101.26% and 99.43% -100.63%, respectively. The linear correlation coefficients were 0.9998 and 0.9996, respectively.
