Gc-9850 Portable Gas Chromatograph for Underground Coal Mine Gas Analysis
Other Products
GC-9850 Specialized for Coal Mine Underground Gas Analysis Portable Gas Chromatograph
Scope of Application:
Coalbed methane, mine gas, goaf gas, sealed area gas
Instrument Introduction:
The mine gas analyzer is specifically designed for gas analysis in coal mines, fire forecasting, and gas hazard identification. This includes the analysis of prediction, forecasting, and unsealing indicators for extinguishment levels. Utilizing a thermal conductivity detector, dual hydrogen flame detector, methane conversion furnace, ten-way valve sampling device, and specialized stainless steel packed columns, it completes the analysis of both macro and micro components of mine gas (O₂, N₂, CH₄, CO, CO₂, C₂H₄, C₂H₆, C₂H₂) in a single injection.
Execution Standards:
AQ/T1019-2006 Chromatographic Analysis of Indicator Gases for Spontaneous Combustion of Coal Seams and Optimal Selection Methods
AQ/T1008-2007 Mine Rescue Regulations
Performance Features:
◆ Based on the new generation high-performance, high-stability GC-9850 gas chromatograph, ensuring reliable and stable operation.
◆ Microcomputer automatically controls the ten-way valve sampling device.
◆ Uses three stainless steel chromatographic packed columns, effectively preventing cross-contamination and ensuring long-term uninterrupted operation.
◆ Employs a three-detector process: thermal conductivity detector, hydrogen flame detector, and an added conversion furnace. Automatically adjusts the sensitivity of the hydrogen flame detector based on methane content to avoid masking trace components behind high methane levels.
◆ Fast analysis speed: completes the analysis of mine gas macro components (O₂, N₂, CH₄, CO, CO₂, C₂H₄, C₂H₆, C₂H₂) in 4-8 minutes with a single injection.
◆ Can be equipped with an electron capture detector for measuring tracer gas SF₆, and a flame photometric detector for measuring gases like H₂S and SO₂.
◆ Comes with a 4/8-liter aluminum cylinder containing multi-component standard mixed gas.
◆ Dual-channel chromatographic workstation, supports Windows XP operating system, allowing flexible storage of chromatographic analysis spectra, data processing, and report printing.
◆ Can be paired with a specialized chromatographic workstation for mine gas analysis. For dual-channel products, spectra from channels A and B can be merged into one spectrum for processing and calculation. Alarm values for various gas concentrations and alkene ratios can be set, with automatic alerts for methane and oxygen concentrations entering the gas component triangle. Results from automatic and manual sampling can be stored in a database. Historical data or trend charts can be printed (or queried) by time or sampling location, displaying the distance between the gas triangle and historical data.
◆ Enables online automatic analysis; by laying pipelines, the instrument can periodically sample automatically, continuously monitoring process sample gas and self-calibrating without manual verification. For areas without pipeline probes, manual sampling detection is available, offering flexibility and reliability.
