制备气相色谱法 preparative gas chromatography
- 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 CH_4 in air and H_2S in N_2,which used in the calibration of gas alarm.Gas chromatography was applied to the analysis of the stability,homogeneity,to make sure the reliability of these gases.
