摘　　要：在气相色谱分析中,采用两阀三柱技术先把气体样品中的重组分反吹掉,然后通过两根HayeSep Q柱与5A分子筛柱把一氧化碳与二氧化碳分离,经过镍触媒转化炉进行加氢转化为甲烷,再通过氢火焰检测器进行检测,实际应用有很好的分离效果,分析数据准确可靠。Using two-valve three-column technology,the heavy components in the gas sample are blown off.Then carbon monoxide and carbon dioxide are separated by two HayeSep Q columns and 5A molecular sieve columns.After hydrogenation and conversion in a nickel catalyst converter,carbon monoxide and carbon dioxide converted into methane,and then detected by a hydrogen flame detector.The practical application has a good separation effect,and the analysis data is accurate and reliable.
