| titleOfInvention | A method for measuring cerium isotope ratio by thermal ionization mass spectrometer |
| abstract | The invention discloses a method for measuring the isotope ratio of cerium by a thermal ionization mass spectrometer. The invention includes three steps of single rhenium band coating, mass spectrometry measurement and data correction. It adopts positive thermal ionization mass spectrometry measurement method, based on Ce + measurement mode, adopts single rhenium band, uses TaF 5 solution as a propellant, and uses different resistance values. The amplifier combination receives the Ce isotopes simultaneously. The method of the invention solves the technical problem that the simultaneous reception of Ce isotopes cannot be realized in the prior art, effectively reduces the isobaric interference of barium in the process of Ce isotope mass spectrometry analysis, and significantly improves the accuracy of Ce isotope ratio measurement Sex and external precision. |
