A method is described for the determination of acetochlor and oxyfluorfen by capillary gas chromatography with FID and an SE-30 capillary column (60 m x 0.53 mm i. d., 1.5 microm), using dibutyl phthalate as the internal standard. The standard deviations for acetochlor and oxyfluorfen concentration(mass fraction) were 0.44% and 0.47% respectively. The relative standard deviations for acetochlor and oxyfluorfen were 0.79% and 0.88% and the average recoveries for acetochlor and oxyfluorfen were 99.3% and 101.1% respectively. The method is simple, rapid and accurate.
描述了一种采用氢火焰离子化检测器（FID）和SE-30毛细管柱（60 m×0.53 mm内径，1.5微米），以邻苯二甲酸二丁酯为内标，通过毛细管气相色谱法测定乙草胺和乙氧氟草醚的方法。乙草胺和乙氧氟草醚浓度（质量分数）的标准偏差分别为0.44%和0.47%。乙草胺和乙氧氟草醚的相对标准偏差分别为0.79%和0.88%，乙草胺和乙氧氟草醚的平均回收率分别为99.3%和101.1%。该方法简便、快速且准确。
