空气中甲烷、氮气中硫化氢气体标准样品的研制

The Preparation of Standard Gas of Methane in Air And Hydrogen Sulphide in Nitrogen

叙述了气体报警仪标定和检测使用的空气中甲烷、氮气中硫化氢气体标准样品的制备,以气相色谱法对其均匀性和稳定性进行考核,确保其数据准确可靠。

This paper reviews the method for preparing standard gas of CH4 in air and H2S in N2, which used in the calibration of gas Mann. Gas chromatography waft applied to the analysis of the stability , homogeneity, to make sure the reliability of these gases.
