Abstract:
1. A method of analyzing data from a mass spectrometer, comprising: a) generating a first mass spectrum corresponding to a known sample and a second mass spectrum corresponding to an unknown sample, b) applying a plurality of perturbations to said second spectrum so as to derive a plurality of perturbed spectra, c) comparing each of said plurality of perturbed spectra to said first mass spectrum, and d) choosing one of said perturbed spectra according to its correlation with said first mass spectrum, wherein the generating step includes generating a plurality of first and second mass spectra during a period of time, and wherein a second mass spectrum used in step (b) is selected by comparing candidate second mass spectra with a plurality of first mass spectra, and selecting a candidate second mass spectrum which contains components which are not in common with components in said first mass spectra.
