介绍了在HP-1(30m×0.53mm×1.50μm)大口径毛细柱上以邻苯二甲酸二戊酯做内标,进样口和检测器温度均为250℃,在柱温220℃下进行分离,用FID检测器对敌稗·草酮复合制剂进行气相色谱定量分析的方法。两种有效成分敌稗、草酮在同一条件下测定,操作简便,方法的线性相关系数均为0.9999,精密度和准确度较好。 Introduced in the HP-1 (30m × 0.53mm × 1.50μm) large-diameter capillary column with dipentyl phthalate as an internal standard, the inlet and the detector temperature are 250 ℃, at a column temperature of 220 ℃ Was separated, and the FID detector was used to conduct gas chromatography quantitative analysis of the compound of propanil and hawthorn. The two active ingredients propanil and hawthorn were determined under the same conditions and the operation was simple. The linear correlation coefficients of the two methods were both 0.9999, and the precision and accuracy were better.
