摘要
介绍了一种采用阀切换和气相色谱质谱联用(以下简称GC-MS)技术的测试方法,利用该方法可以实现对轻烃中微量甲醇、二甲醚和甲基叔丁基醚的测定,试验结果表明该测试方法具有样品适用范围广,分析结果准确的特点,解决了轻烃分析中大量烃类组分对微量甲醇、二甲醚和甲基叔丁基醚测定的干扰问题,能够为乙烯原料质量监测提供参考数据。
A determination method with the switch valve and gas chromatography mass spectrometry was introduced. This method can determine trace methanol, dimethyl ether and methyl tert-butyl ether in light hydrocarbon. The test results show that the method is sample and its applicability is wide, and the analysis results are accurate, it can provide a reference for ethylene raw material quality monitoring.
