In the mining industry, especially in coal mines, the explosion of some flammable gases is one of the main factors causing coal mine accidents at present.In order to reduce the occurrence of such accidents, each mine is equipped with monitoring personnel who use a handheld gas monitoring device. Although this handheld gas monitoring device can provide some monitoring, its accuracy is low and it cannot detect factors such asCOThe concentration of gas and other explosive substances is not ideal for monitoring.Gas detection in underground coal minesgas chromatographGC-9860KIt is fromGC-9860gas chromatographComponents including host, effective chromatography column, methane converter, thermal conductivity detector, and hydrogen flame detector，Adopting microcomputer control，Can achieve automatic switching of valves and detector signals, configured with4Road gasflowQuantity sensor，Connected to the computer through a data cable, using mine gasbodyA dedicated chromatographic workstation collects signals and processes themanalysisData processingpreservation.

Gas detection in underground coal minesgas chromatographGC-9860KManufacturing based on chromatographic principles, utilizingManual or automaticThe switching of the ten way valve can achieveH2, O2, N2, CH4,CO, CO2, C2H4, C2H6, C2H2Composition mixturegasPerform rapid separation and high-sensitivity detection. docoalminebelowAtmospheric analysis, fire prediction、Assessment of gas explosion hazard levelrapid analysisdistinguish,at the same timeSatisfy the gas constant of coal mines（%Concentration, trace amount（ppmWhole process analysis of concentration components and inorganic/organic gas components.

■Gas detection in underground coal minesgas chromatographmain features
1、The thermal conductivity detector and the dual hydrogen flame detector work simultaneously, and the three signal channels collect data simultaneously; The dual conversion furnace system greatly improves the analysis efficiency and accuracy.
2、useManual or automaticTen way valveQuantitative tubeOne injection15Complete the analysis of all components and determine the degree of explosion hazard within minutes,haveShort analysis timeAdvantages such as accurate results.
3、equip4Road gas flow display, easy and convenient to operate;Fast analysis speed:4～15Complete mine gas explosion gas constant within minutesO2、N2、CH4、CO、CO2、C2H6、C2H4、C2H2Waiting for trace amounts of fire gasesCH4、CO、CO2、C2H4、C2H6、C2H2Analysis of components.6～15Within minutes, complete the analysis of all components of gas explosion and the determination of explosion hazard level in one injection (explosion triangle method).

4、Manual and automatic injection can be freely selected, equipped with32The road channel sampling machine can achieve uninterrupted cyclic sampling analysis, automatically print analysis reports, and can also be used through the networkremotetransmit data.
