摘　　要：置换氮气^([1])中的常量氧和可燃气含量分析需要3台色谱仪,1台色谱仪分析总烃,1台色谱仪分析氢气,1台色谱仪分析常量氧气,分别进3次样才能出结果,且分析时间较长。优化方法设计,采用1台色谱仪、1次进样,双通道双检测器实现氮气中常量氧气和可燃气含量的检测,分析时间缩短到优化前的五分之一。The analysis of constant oxygen and combustible gas content in replacement nitrogen requires three chromatographs:one for total hydrocarbons,one for hydrogen,and one for constant oxygen,with three separate sample injections needed to obtain results,which takes a long time.The optimized method is designed to use one chromatograph and one sample injection,with a dual-channel dual detector to detect constant oxygen and combustible gas content in nitrogen.The analysis time reduced to one-fifth of the time before optimization.

关 键 词：置换气 时间缩短 优化 同时检测
