摘要
介绍一个新开发的毛细管气相色谱测定环丁砜纯度的试验方法。该方法载气为氦气，样品径ＣＢＰ２０或ＨＰ－１石英毛细管柱分离，采用 ＴＣＤ检测，归一化法定量。环丁砜纯度分析数据 ＲＳＤ ０.０１％；样品单次分析时间１５ｍｉｎ，方法操作简单、快速，数据精密、准确，适用于环丁砜纯度的质控分析。
A newly developed method for the purity analysis of sulfolane by CGC-TCD is introduced. The precision and accuracy of the data demonstrated that it is suitable for the requirement of analysis of sulfolane in the course of control on the quality.
