Mine Gas Analysis Special Gas Chromatograph

Which gases in mine gas are primarily analyzed by the dedicated gas chromatograph for mine gas analysis? What is the purpose of analyzing mine gas?

Main mine gases include: CO, O₂, N₂, CO₂, CH₄, C₂H₄, C₂H₆,  C₂H₂, C₃H₈

Gas chromatography detects the composition and content of mine gas components for fire prediction and gas hazard identification. This includes analysis for prediction, forecasting, and unsealing indicators of extinguishment levels. Using a thermal conductivity detector, dual hydrogen flame detector, methane conversion furnace, ten-way valve sampling device, and stainless steel packed column, a single injection completes the analysis of both macro and micro components of mine gas (O₂, N₂, CH₄, CO, CO₂, C₂H₄, C₂H₆, C₂H₂).
