Mine gas chromatograph

Mine gas chromatographProduct Introduction：

1. Fully automated operation: The instrument is automatically controlled by a microcomputer, achieving uninterrupted cyclic sampling from 1 to 32 points (expandable to more than 32 points), automatic injection and analysis of three columns simultaneously, automatic printing of analysis reports, and data transmission through the network.
2. High stability: Dual hydrogen flame, thermal conductivity detector, dual column box, three column parallel connection, equivalent to the configuration of two gas chromatographs combined into one. The dual column box device ensures the analysis of 10 gas components such as carbon monoxide, alkenes, and alkanes at different temperatures in different column boxes, ensuring the separation degree of each analytical component, greatly improving the analysis speed and accuracy, and ensuring the reliability of prediction and forecasting.
3. Safety and longevity: Three pre column devices prevent contamination of the three analytical columns, ensuring long-term uninterrupted operation of the entire instrument.
4. Rapid analysis: The instrument is equipped with a special blowback device, which greatly shortens the time of each analysis cycle. Complete the analysis of constant O2, N2, Co, Co2 and trace amounts of Co, CH4, C2H2, C2H4, C2H6 within 4-8 minutes with a single injection, providing data for rapid fire detection. Complete the analysis of constant O2, N2, CH4 and trace amounts of Co, Co2, CH4, C2H2, C2H4, C3H8 within 10 minutes.
5. Coexistence of routine analysis and patrol monitoring: For certain special locations (without sampling points), routine methods can also be used to collect gas samples back to the laboratory using a bladder and complete routine analysis.
6. Automatic/manual conversion function: With this function, it is easy to achieve automatic monitoring of the beam tube and efficient conversion of the universal laboratory gas chromatograph.
7. Multifunctional: It can also achieve testing and analysis of the components of mine gas, tracer sulfur hexafluoride, sulfur dioxide, and other components.
8. The minimum detection concentration of gas components that mainly indicate the natural combustion process of coal seams:
Whole component: CO ≤ 0.5ppm
C2H4≤0.1ppm
C2H2≤0.5ppm
CO2 ≤2.00ppm
C2H6、C3H8≤0.5ppm
CH4 ≤0.1ppm
System error ≤ 1.0%
