摘要
主要介绍天然气气相色谱分析方法和数据处理方法。天然气的组成测定采用热导检测器和氢火焰电离检测器双检测器检测,使用填充柱和毛细管柱分离。在进行结果分析时,考虑到天然气组成复杂和仪器的检测器对天然气各组分的线性响应,可以采用外标-校正归一化色谱法定量,此方法能够准确、简易地测定天然气的组成。
The gas chromatography analysis and data processing methods for the determination of natural gas are introduced. The natural gas composition is determined by a dual detector which includs thermal conductivity detector and hydrogen flame ionization detector; and it is separated by a packed column and capillary column. Considering the complexity of natural gas composition and the linear response of detector to each composition, the external standard- corrected normalized chromatography is employed to quantify in the process of result analysis, this method can accurately and simply determine the composition of natural gas.
