Determination of CO2 in Liquefied Natural Gas
Determination of CO2 in Liquefied Natural Gas Details:

Name: Packed column
Stationary phase: polymer pellets
Granularity: 60-80 mesh
Specification: 8m*3mm
Model: GDX-104
Application: GB/T 38753-2020 Liquefied Natural Gas

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.
