研究了气相色谱测定氯化胆碱中残留氯乙醇的方法。方法回收率为１００．２％～１０４．２％，相对标准偏差０． ５％，线性关系良好，方法检测限为 １． ０８ｕｐ／ｍＬ。
The method of gas chromatography for the determination of residual chloroethanol in choline chloride was studied. The recovery rate of the method was 100.2% ~ 104.2% with relative standard deviation of 0. 5%, a good linear relationship, the detection limit of 1 method. 08up / mL.
