摘要
叙述了气体报警仪标定和检测使用的氮气中氧、氮气中二氧化硫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 of preparing standard gas of SO2 in N2 and 02 in N2, which used in the calibration of gas Mann. Gas chromatography was applied to analyze of the stability and homogeneity, to make sure the reliability of these gases.
