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

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.
