Methane/hydrocarbons/transformer oil gas analysis chromatography

Gas analysis chromatography can be used for underground gas analysis in coal mines, and for the analysis of dissolved gases in transformer oil, including H2, O2, CO, CO2, CH4, C2H6, C2H4, and C2H2. The analysis of H2, O2, N2, CO, CO2, and hydrocarbon gases in gases such as coke oven gas, petroleum gas, and liquefied gas is widely used in various analyses of industrial gases.
The instrument adopts a microcomputer automatic control system and a large Chinese LCD screen display. The design is flexible and reasonable, and it is equipped with thermal conductivity and dual hydrogen flame detectors, methane conversion furnace, gas injection valve, and various chromatographic columns. The gas path process used achieves a single injection and three detector technology to complete the analysis of constant and trace components of gases such as H2, O2, N2, CO, CO2, CH4, alkanes, alkenes, alkynes, etc.
