自制前处理装置与四极质谱仪联用分析稀有气体组分

Rare gas component measurement with self-designed pretreatment unit and Quadrupole Mass Spectrometer

摘要: 自制稀有气体前处理装置与四极质谱仪联用,以空气中稀有气体含量为标准,分析样品气体中稀有气体的百分含量。该方法灵敏度高,He,Ar分析具有较好的精确度。将之用于天然气和沉积岩群体包裹体中稀有气体组分分析,分析结果能够满足地质研究的要求。

Abstract: According to the rare gas component in air,the content of rare gas in sample gas is measured with self-designed pretreatment unit and Quadrupole Mass Spectrometer(QMS).The method is highly sensitive and is accurate in He and Ar analyses.It is applied in rare gas component analyses of natural gas and grouped inclusions in sedimentary rocks.The results satisfy the needs of geology research.
