采用内涂OV - 1固定液的石英毛细管气相色谱柱和FID检测器 ,以邻苯二甲酸二丁酯为内标物 ,在适宜的条件下对异丙草胺、莠去津两种组份同时进行定量分析。本方法中异丙草胺和莠去津变异系数分别为 0 .2 9%和 0 .5 8% ,平均回收率为 99.95 %和 10 0 .13% ,线性相关系数皆约为 0 .9999。
A capillary column with FTI and FID detector was used to immobilize OV - 1 in the solution. Dibutyl phthalate was used as an internal standard. Under the appropriate conditions, At the same time quantitative analysis. The coefficients of variation for both isopropylamine and atrazine in this method were 0.29% and 0.58%, respectively. The average recoveries were 99.95% and 10 .13%, respectively. The linear correlation coefficients were all about 0.9999.
