Beijing Lingtian Coal Mine's portable gas analyzer (portable gas chromatograph) passed coal safety and explosion-proof certification
（便携式气相色谱仪） Portable gas analyzer for coal mine (portable gas chromatograph)
， 主要应用于对矿井下的空气成分的多组份进行分析、矿井作业现场对矿井气体全组份分析、实验室分析、早期预测预报煤层自燃发火、监测煤自燃过程中气体组份浓度变化规律、防止自燃发火和瓦斯爆炸。 Portable gas analyzers for coal mines are mainly used to analyze the multi-components of the air composition under the mine, the full-component analysis of the mine gas at the site of the mine, laboratory analysis, early prediction and prediction of coal seam spontaneous combustion, and monitoring of coal spontaneous combustion Gas component concentration changes, prevent spontaneous combustion and gas explosion.
When the instrument is used for on-site analysis of mine operations, direct sampling is used on site, and auxiliary sampling by other equipment is not required. After the sampling is completed, the sampling can be completed only by turning on the sampling switch.
