一种分析天然气组分的多维色谱法

Composition Analysis of Natural Gas by Multi-Dimensional Gas Chromatography

介绍了一种快速分析天然气组成的多维气相色谱分析方法。通过确定色谱分析条件和阀切换时间,实现了一次进样完成样品中所有组分的分离检测。数据处理时采用了标准气体进行定性,并用面积校正归一化法进行定量计算。该方法重复性好,准确度高,并可用于炼厂气,热模拟产物的分析。

This paper introduces a method to detect natural gas components by multi-dimensional gas chromatography. The analysis conditions of gas chromatography and valve switching time were confirmed,so it can detect all components with once sample injection. The standard gas was used for qualitative analysis and area normalization method was used for quantitative calculation. This method is highly reproducible and precise, moreover,the refinery gas and thermal simulation products can be detected by this method.
