采用气相色谱法，以癸二酸二正丁酯为内标物，对新研制的复合型稻田除草剂26％丁··西乳油进行了一次性定量分析。色谱条件为5％SE-302m×3mm的玻璃柱，柱温为210℃，检测温度为230℃。方法的回收率为98．62％～100．77％，线性相关系数大于0．999。方法准确、简便、快速。
Using gas chromatography, di-n-butyl sebacate as an internal standard, the newly developed composite rice field herbicide 26% Ding West emulsion was a one-time quantitative analysis. The chromatographic conditions were 5% SE-302m × 3mm glass column, the column temperature was 210 ℃, the detection temperature was 230 ℃. The recovery rate of the method was 98.62% ~ 100.77%, and the linear correlation coefficient was greater than 0.999. The method is accurate, simple and fast.
