建立一种同时分析腈菌唑和三唑酮的气相色谱分析方法。试样用丙酮溶解,以邻苯二甲酸二戊酯为内标,使用HP-5毛细管柱和气相色谱氢火焰检测器,对试样中的腈菌唑和三唑酮进行气相色谱分离和测定。结果表明,腈菌唑和三唑酮的线性相关系数分别为0.9997和0.9995,标准偏差为0.015和0.083,变异系数分别为0.63%和0.72%,平均添加回收率为99.6%和99.3%。
A gas chromatographic method for the simultaneous analysis of myclobutanil and triadimefon was established. The sample was dissolved in acetone and diamyl phthalate was used as the internal standard. The myclobutanil and triadimefon were separated and determined by gas chromatography using HP-5 capillary column and gas chromatograph hydrogen flame detector . The results showed that the linear correlation coefficients of myclobutanil and triadimefon were 0.9997 and 0.9995 respectively. The standard deviations were 0.015 and 0.083. The coefficients of variation were 0.63% and 0.72%, respectively. The average recoveries were 99.6% and 99.3% respectively.
