摘要
介绍了一种毛细管气相色谱法测定 1 ,3-丁二烯中炔烃杂质含量的新试验方法。该方法以氮气为载气 ,采用氢火焰离子化检测器 ,样品经分离后 ,采用外标法定量 ,操作简便、准确。该方法还可用于 1 ,3-丁二烯纯度分析。
A new test method, in which alkyne impurity content in 1,3-Butadiene is determined by a capillary gas chromatograph,was introduced. Nitrogen is taken as carrier, and hydrogen flame ionization detector adopted. After separating, quantitative analysis of the sample is made by external scale method. Its operation is simpler and more exact. The method can be applied to determination of purity of 1,3-Butadiene.
