摘要
叙述了用于检测分析、仪器校准使用的氮气(空气)中甲烷气体标准样品的研制,以气相色谱法对其均匀性和稳定性进行考察,确保其数据可靠。
This paper reviews the method for preparing standard gas sample of methane in nitrogen（air）,which used in the calibration of instrument or test.Gas chromatography was applied to the analysis of the homogeneity and stability to make sure the reliability of this gas.
