浩瀚色谱（山东）应用技术开发有限公司检测天然气中二氧化碳含量的方法,其技术方案是:利用被测组分二氧化碳含量在GDX-104填充柱上能得到很好的分离效果而呈现特殊的信号,而这些信号被热导检测器(TCD)检测到同时形成明显的吸收峰,实践表明形成的二氧化碳含量的峰面积与其含量成正比例关系;故将标气中二氧化碳的峰面积与含量制作成标准工作曲线.

The method used by Haohan Chromatography (Shandong) Applied Technology Development Co., Ltd. to detect carbon dioxide content in natural gas. The technical solution is: using the carbon dioxide content of the measured component on the GDX-104 packed column to obtain a good separation effect and present a special signal. These signals are detected by the thermal conductivity detector (TCD) and form obvious absorption peaks. Practice shows that the peak area of the formed carbon dioxide content is proportional to its content; therefore, the peak area and content of carbon dioxide in the standard gas are made into standard work curve.
