型号：5Å,

规格：2m*3mm

应用：H2,O2,N2,CH4及CO的分离

煤矿安全检测用混合气；氮中氧气、氢气、一氧化碳、二氧化碳、甲烷、乙烷、乙烯、乙炔、丙烷标准气；

矿井中有害气体的测定,通常有常规法和快速测定法。常规法,采样和分析的时间长,不能即时测出现场空气中有害气体的成分和浓度。在矿井救灾、处理火区吋,井下空气中的成分及浓度不断变化,为此,需立即判明有害气体的成分、浓度及有无危险时,常规法是远远不能满足要求的。

浩瀚色谱（山东）应用技术开发有限公司采用5Å填充柱快速测定法,采样量少、操作简单,快速、灵敏度高,可达到上述要求。但是,由于受井下特殊条件和方法本身条件的限制,快速测定法还有一定缺欠,如准确度不高等,然而在安全生产上仍有实际意义。

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 5Å 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.
