型號：5?,

規格：2m*3mm

應用：H2,O2,N2,CH4及CO的分離

煤礦安全檢測用混合氣；氮中氧氣、氫氣、一氧化碳、二氧化碳、甲烷、乙烷、乙烯、乙炔、丙烷標準氣；

礦井中有害氣體的測定,通常有常規法和快速測定法。常規法,采樣和分析的時間長,不能即時測出現場空氣中有害氣體的成分和濃度。在礦井救災、處理火區吋,井下空氣中的成分及濃度不斷變化,為此,需立即判明有害氣體的成分、濃度及有無危險時,常規法是遠遠不能滿足要求的。

浩瀚色譜（山東）應用技術開發有限公司采用5?填充柱快速測定法,采樣量少、操作簡單,快速、靈敏度高,可達到上述要求。但是,由于受井下特殊條件和方法本身條件的限制,快速測定法還有一定缺欠,如準確度不高等,然而在安全生產上仍有實際意義。

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.
