Mixed gas for coal mine safety testing; standard gas of oxygen, hydrogen, carbon monoxide, carbon dioxide, methane, ethane, ethylene, acetylene, and propane in nitrogen;

The determination of harmful gases in mines usually includes conventional methods and rapid determination methods. The conventional method takes a long time for sampling and analysis, and cannot immediately measure the composition and concentration of harmful gases in the air in the field. In mine disaster relief and fire treatment areas, the composition and concentration of the underground air are constantly changing. For this reason, when it is necessary to immediately determine the composition, concentration and danger of harmful gases, conventional methods are far from meeting the requirements.

Haohan Chromatography (Shandong) Applied Technology Development Co., Ltd. adopts 5? packed column rapid determination method, which has small sampling volume, simple operation, fast speed and high sensitivity, which can meet the above requirements. However, due to the limitations of the underground special conditions and the conditions of the method itself, the rapid determination method still has certain shortcomings, such as low accuracy, but it still has practical significance in safe production.
