Abstract
A method of processing mass spectral data is provided. The method comprises identifying one or more ion peaks in mass spectral data, and for each of one or more ion peaks identified in the mass spectral data: determining, from the mass spectral data, a value indicative of an intensity loss for the ion peak and evaluating a charge state for the ion peak using the intensity loss-indicative value.
