GC-SCD联用分析轻质液态烃中总硫

Analysis of total sulfur in light liquid hydrocarbons by GC-SCD

文章介绍了通过GC-SCD联用,利用安捷伦DEACT毛细管色谱柱,根据保留时间定性,峰面积外标法定量的方法分析轻质液态烃中总硫。得到的结果重复性较好,与传统方法相比,该方法具有分析时间短、重复性好、检测限低、对操作者要求不高、对硫等摩尔相应等优点,是一种分析液态轻质烃中总硫的可选方法。

This paper introduces the use of GC-SCD in combination with the Agilent DEACT capillary column to determine the total sulfur in light liquid hydrocarbons based on the retention time qualitative and peak area external standard method. The obtained result has good repeatability. Compared with the traditional method, the method has the advantages of short analysis time, good repeatability, low detection limit, low requirement on the operator, and equivalent equivalence of sulfur, and is an analysis of liquid light. An alternative method for total sulfur in hydrocarbons.
