Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a method suitable for deconvoluting a convoluted spectrum, such as data acquired from a mass spectrometer. SOLUTION: The method comprises a step of receiving a convoluted spectrum for a group of overlapping isotopic clusters; and a step of determining a normalized peak intensity for each isotope cluster in the convoluted spectrum by determining the main summary isotope peak for each of a plurality of main summary isotope peaks, and for each main summary isotope peak determined, subtracting known intensity contributions for at least one lower mass isotope cluster up-mass side peak, and at least one higher mass isotope cluster and at least a lower-mass side peak from and adding known intensity contributions for at least one lower-mass side peak and at least one higher-mass side peak of the isotopic cluster to respective main summary isotope peak.
