气相色谱法测定1,2,4-三甲基苯纯度及其烃类杂质的研究

摘要

本工作采用气相色谱仪,从色谱典型操作条件的确定、测量结果准确度和精密度的确认对测定1,2,4-三甲基苯纯度及其烃类杂质进行研究。方法推荐键合/交联聚乙二醇玻璃毛细管色谱柱,使用氢离子化（FID）检测器,柱温采用分阶的升温程序%It was studying on chromatographic typical operating conditions,accuracy and precision. The cross-linked polyethylene glycol glass capillary columns were used,and the FID detector,and the programmed temperature in gas chromatography.
