摘要
通过实验和数据说明了空分装置生产的液氧经汽化后进入配有气体纯化器、放电离子化检测器和H ayesep S 30″×1/8″填充柱的气相色谱仪,用纯化后的高纯氦作为载气,经色谱系统分离和检测,由色谱工作站采集数据并绘成色谱图,用高纯氦配制的乙炔标准气进行外标法定量,测定液氧中微量乙炔含量的方法。
Lox from air separation equipment evaporated by vaporizer is injected into the gas chromatogram which have gas purifier, DID detector, Hayesep S（30“× 1/8”） column as configuration. The carrier gas is super purity helium purified by gas purifier. The sample is separated and measured by chromatogram system. The workstation of chromatogram collected data and drew a graph. Finally the trace ethyne concentration in lox is measured by standard gas confected by super purity helium using external standard method.
