Abstract

Sample molecules are ionized producing a beam of ions using an ion source. A plurality of ion extractions are performed on the beam of ions using a TOF mass spectrometer. Electrical detections from each extraction are measured using an ADC, producing a mass sub-spectrum for each extraction. An ion m/z from the plurality of mass sub-spectra is selected. For each mass sub-spectrum, the amplitude and m/z of an ion within a m/z tolerance of the ion m/z is assigned to the corresponding amplitude band of a plurality of predetermined amplitude bands, producing a plurality of amplitude and m/z values for the each amplitude band. For each amplitude band of the plurality of predetermined amplitude bands, the plurality of amplitude and m/z values are combined into a peak, resulting in a plurality of peaks corresponding to the plurality of predetermined amplitude bands.
