How to configure a noble gas analyzer
Thread Content
How are analyzers generally configured for crude neon-helium and lean krypton-xenon gases? What analyzer should be configured? Those who have used it, please share your experience. Thank you
The analytical monitoring of inert gases generally involves measuring the impurities present in them. The inert gas itself serves as the background component, while the impurities typically include oxygen, nitrogen, moisture, carbon dioxide, trace amounts of light hydrocarbons, etc., as well as the impurities that exist within the inert gas itself. The best method for determining these impurities is gas chromatography; oxygen can be analyzed using an electrochemical analyzer, while moisture can be measured with a dedicated moisture analyzer (or dew point meter). It’s difficult to give a specific answer to such a general question; I suggest you contact a member named @huapiaoxu521, who has extensive knowledge in the analysis of impurities in pure gases.
1. Crude Ne-He: Thermal conductivity chromatography is mainly used to analyze the percentage contents of Ne, He, and H2 in Ne-He mixtures； 2. Crude Kr-Xe: Magnetic oxygen analyzer for oxygen analysis in crude Kr-Xe ； Infrared analyzer for CH4 and CO2 analysis in crude Kr-Xe ； Total hydrocarbon analysis of Kr-Xe mixtures: Hydrogen flame chromatography is used to analyze the total hydrocarbons in Kr-Xe mixtures ； A thermal conductivity chromatograph is used to analyze the percentage contents of Kr, Xe, and O2 in a Kr-Xe mixture.
