【摘要】：建立一套气相色谱检测方法,分析条件如下:不锈钢色谱柱(6 m×3 mm);固定液为邻苯二甲酸二壬酯和β-β′-氧二丙腈的混合物,混合比例为1∶1,涂布浓度为20%,载体为6201红色担体,载体颗粒的粒径为1.65~1.98 mm;载气为氢气,流量40m L/min,柱温35℃,气化温度100℃,热导池检测器温度110℃。检测方法的相对标准偏差在0.39%~2.78%之间,加标回收率在94.1%~104.3%之间,操作简洁、分析快速、结果准确。
[Abstract]:A set of gas chromatographic method was established. The analytical conditions were as follows: stainless steel column was 6 m 脳 3 mm, the stationary solution was a mixture of dinonyl phthalate and 尾-尾 -dioxy dipropionitrile, the mixture ratio was 1: 1, the coating concentration was 20 and the carrier was 6201 red support.The particle size of the carrier is 1.65 ~ 1.98 mm, the carrier gas is hydrogen, the flow rate is 40 mL / min, the column temperature is 35 鈩，
