Oxygen isotope concentration measuring apparatus and oxygen isotope concentration measuring method

摘要

Problem to be solved: to provide an oxygen isotope concentration measuring apparatus and an oxygen isotope concentration measuring method capable of measuring three kinds of oxygen isotopes contained in a liquid sample or a gas sample with higher accuracy.An oxygen isotope concentration measuring apparatus (1) for measuring three kinds of oxygen isotopes contained in a sample;Having a double sorted magnetic field type mass spectrometer (29)A double sorted magnetic field type mass spectrometer (29) isA total ion analysis department for extracting and analyzing total ionsAn ion component extraction part extracting all the ion components from oxygen, andAn oxygen isotope concentration measuring part which measures the concentration of oxygen isotopes from mass components and oxygen ion components.AndIn the oxygen isotope concentration measurement partThe peak area of the ion component derived from the oxygen is measured.Calculate oxygen isotope concentrationOxygen isotope concentration measuring apparatus (1).And an oxygen isotope concentration measuring method.Diagram
