SQM_1气相色谱仪是一台以脉冲加热、气相色谱法测定钢中氢、氧含量的专用气体分析仪器。钢样在脉冲炉中加热熔化,析出氢,一氧化碳,同时氮也释放出来。在本仪器所设定的条件下,用气相色谱分离氢、氮和一氧化碳时,氮峰灵敏度低,氢峰与氮峰的分辨率也低,故不适于做氮的定量分析,作者用601碳分子筛(上海试剂厂)和 SQM_1 Gas Chromatograph is a dedicated gas analysis instrument for the determination of hydrogen and oxygen in steel by pulse heating and gas chromatography. Steel samples were heated and melted in a pulsed oven to precipitate hydrogen, carbon monoxide, and nitrogen was also released. Under the conditions set by this instrument, when the separation of hydrogen, nitrogen and carbon monoxide by gas chromatography, nitrogen peak sensitivity is low, the resolution of hydrogen peak and nitrogen peak is low, so it is not suitable for quantitative analysis of nitrogen, the author 601 carbon Molecular sieve (Shanghai Reagent Factory) and
