摘　　要：目的:通过对分子筛制氧机生产的富氧气体组分分析,为分子筛制氧机的注册与监督检验工作做出针对性建议。方法:采集不同工作时长的分子筛制氧机生产的富氧气体,通过气相色谱分析仪测试富氧气体中甲烷、二氧化碳和一氧化碳的含量,利用氧气分析仪测得氧气含量。结果:甲烷、二氧化碳、一氧化碳的含量很小,随分子筛制氧机工作时间变化,波动较小。氧气含量由工作1小时的93.3%变化为工作8小时的93.0%。结论:注册检验过程中,建议在不同时间点多次采集气体样本测试富氧气体的组分,确保分子筛长时间工作生产的富氧气体仍能够满足标准要求;充分考虑一氧化碳的有毒性、危害性,应将"一氧化碳浓度"列入监督检验项目中。Objective:Making suggestions for registration and supervision test of molecular sieve oxygen generator through performing component analysis on the oxygen-rich gas.Methods:Collect the oxygen-rich gas at different times while the molecular sieve oxygen generator working.A gas chromatographicanalyzer is used to analyze the contents of the methane,carbon dioxide and carbon monoxide.An oxygen analyzer is used to analyze the content of oxygen.Results:The content of methane,carbon dioxide and carbon monoxide is very small,and changes little over time.The content of oxygen changes from 93.3%at the first hour to 93.0%at the eighth hour.Conclusion:Suggest to take more test of the oxygen-rich gas in the registration test,to ensure the oxygen-rich gas is qualified after long time working.Considering the toxicity and harmfulness of carbon monoxide,the"Carbon monoxide concentration"should be tested in supervision test.
