    Abstract
  • A rare gas purification and accumulation system is designed and used in analysis of 4He abundance in natural gas together with mass spectrograph.Sensitivity of 4He is calculated.The system is proved reproductive.Data from natural gas analysis are compared with those from Mat271 mass spectrograph,and deviation is less than 10%.Natural gas from the Puguang and Jiannan gas fields in the Sichuan Basin is analyzed,indicating that,studies of 4He abundance in natural gas is significant for age research of natural gas source rocks and accumulation formation.
