Abstract

A method for correcting mass spectral data obtained for a sample is described, where the mass spectral data is a time-of-flight mass spectral data. The method includes receiving mass spectral data obtained from a sample, the mass spectral data being indicative of an ion abundance. The method further includes applying a correction function to the mass spectral data based on the ion abundance indicated by the mass spectral data and on one or more trapping parameters associated with the mass spectral data. The correction function defines correction values for the mass spectral data for a range of ion abundances and for a range of trapping parameters.
