Abstract
A method for oxygen-17 isotope atomic fraction determination provides oxygen gas introduction into mass spectrometer, and their molecular ionization in ionization chamber by bombing therewith electrons; ionized substance ionization by means of mass spectrometer analyzer; ions with mass: 32, 33, 34, 35, 36 intensity measurement; and isotope oxygen-17 atomic fraction determination with formula having three different mass lines: m/z=32,33,34; m/z=32,33,35; m/z=32,33,36; m/z=32,34,36; m/z=32,35,36; m/z=33,35,36; m/z=34,35,36 და m/z=33,34,35.
