Abstract
A data acquisition method for a mass spectrometer includes providing at least one ion source for generating ions; not fragmenting or less fragmenting the ions when a collision cell is in a first working mode; recording a mass spectrum of the ions generated in the first working mode; selecting more than one ion from the ions, the more than one ion being distributed in a plurality of discontinuous mass-to-charge ratio channels; partially fragmenting the selected ions when the collision cell is in a second working mode; recording a mass spectrum of the ions generated in the second working mode; and, repetitively executing the above steps for several times. The ions distributed in the discontinuous mass-to-charge ratio channels is always selected during the subsequent repeated execution, until the ion intensity of the selected ions is less than a set value.
