GC-4000A (08A/08B/08C) special gas chromatograph for coal mine

The GC-4008 series coal mine gas chromatograph is a device equipped with detectors such as thermal conductivity and hydrogen flame. A dedicated coal mine gas chromatograph with multiple specialized chromatographic columns can be used for mine rescue analysis and monitoring the analysis of gases during the oxidation and self-heating process of coal seams, improving the accuracy of early prediction and forecast of spontaneous combustion. It can measure the changes in the concentration of gas components in a closed fire area, determine the degree of extinguishing in a closed fire area and the risk level of gas explosion, providing scientific data for decision-makers.
