Abstract
A method for determining an isotopic profile for a molecule is provided. The isotopic profile is indicative of an isotopic content for the molecule. The method comprises mass selecting ions of the molecule in a mass window, the mass window excluding a mass for a monoisotopic molecular ion and including a mass for at least one isotopic variant of the monoisotopic molecular ion. The method comprises fragmenting the mass selected ions into fragment ions, performing mass analysis on one or more of the fragment ions to produce a mass spectrum, and determining the isotopic profile for the molecule, the isotopic profile comprising at least one data value. Each data value is calculated for a fragment ion as a function of intensities of multiple peaks in the mass spectrum. A computer program is provided. A mass spectrometry system is provided. A method for identifying a sample is provided.
