Portable micro gas chromatograph for coal mine gas analysis

The 700 portable GC coal mine gas analysis portable micro gas chromatograph integrates a micro gas chromatography analysis module, communication module, main control display module, and gas source battery module. The carrier gas can be hydrogen gas generated by a built-in hydrogen generator (electrolytic water hydrogen production does not require inflation) or a built-in high-pressure steel cylinder (high-pressure inflation).

　　Portable micro gas chromatograph for coal mine gas analysisIt is a dual channel micro gas chromatography system that can be used simultaneously for the determination of components such as hydrogen, methane, ethane, ethylene, acetylene, carbon monoxide, carbon dioxide, oxygen, and nitrogen in mine gas.

The instrument integrates a micro gas chromatography analysis module, communication module, main control display module, and gas source battery module. The carrier gas can be hydrogen gas generated by a built-in hydrogen generator (electrolytic water hydrogen production does not require inflation) or a built-in high-pressure steel cylinder (high-pressure inflation).
