  • Determination of chemical empirical formulas of unknown compounds using accurate ion mass measurement of all isotopes
    Patent number: 7855356
    Abstract: A method of determining an empirical formula of an analyte ion from a measured mass spectrum including a main peak and one or more isotope peaks. The method comprises comparing a relative isotopic intensity of the measured isotope peak to a calculated relative isotopic intensity of an isotopic ion of a proposed empirical formula and comparing a relative mass defect of the measured isotope peak to a calculated relative mass defect of the isotopic ion of the proposed empirical formula. The proposed empirical formula is identified as a potential candidate for the analyte ion based on these comparisons.
    Type: Grant
