The atomic fractions of the isotopes of oxygen are determined in nitrogen oxide and water by conversion into molecular oxygen. Determination of the isotopes of oxygen in molecular oxygen is made utilizing intensities of ionic currents of various mass numbers and the atomic fraction of oxygen isotopes, which are calculated by different formulas, thus verifying the possible background superimposition of any molecular line and that significantly increases the reliability and accuracy of the method.
