氯化胆碱中残留氯乙醇的气相色谱测定

Analytical Method of Determining Residual Ethylene Chlorohydrin in Choline Chloride with Gas Chromatography

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 analysis of residual ethylene chlorohydrin in choline chloride by Gas Chromatography using column in filled with fixed phase of GDX - 103 were studied. Its retrievability is 100. 2% - 104. 2% and opposite standard deviation is 0. 5 %. Linearity is favourable and minimum termination of method is 1. 1ug/ml.
