GC-4085B Mine Gas Multi point Parameter Chromatography Automatic Analyzer is the main analysis unit of the national "Eighth Five Year Plan" scientific and technological research project "Mine Lifting Multi point Parameter Chromatography Automatic Analyzer". This instrument applies gas chromatography analysis technology to identify the main indicators of coal seam spontaneous combustion temperature rise process (slow oxidation, accelerated oxidation, and intense oxidation stages), with other hydrocarbon gas components as auxiliary indicators, to grasp the trend of coal seam spontaneous combustion changes, guide mines to take targeted fire prevention and extinguishing measures, and achieve the goal of early prediction and forecasting of coal seam spontaneous combustion status and unsealed fire areas.

Main technical features and indicators

Fully automated operation:The instrument is automatically controlled by a microcomputer, achieving uninterrupted loop sampling from 1 to 32 points (expandable to 32 points), and automatic injection and analysis of three columns simultaneously;

High stability:Double column box for temperature control, three column parallel connection, and methane conversion furnace device. Dual hydrogen flame, thermal conductivity detector, dual column box, three column parallel connection, equivalent to the combination of two gas chromatographs. The dual column box device ensures the analysis of 10 gas components such as carbon monoxide and alkenes at different temperatures in different column boxes, ensuring the separation degree of each analysis component, greatly improving the analysis speed and accuracy, and ensuring the reliability of prediction and forecasting.

Safety and longevity:Three pre column devices are used to prevent contamination of the three analytical columns and maintain the continuous operation of the entire instrument for a long time. Large screen LCD display.
