Abstract
A data acquisition and analysis method for a mass spectrometer includes providing at least one ion source for generating ions, the generated ions containing ions of a substance to be analyzed; dividing the full mass-to-charge ratio range of the ions of the substance into several mass-to-charge ratio windows, feeding ions corresponding to different mass-to-charge ratio windows into a collision cell to fragment at least part of the corresponding ions, and recording mass spectra of the ions passing through the collision cell as corresponding product ion spectra; obtaining a mass-to-charge ratio window corresponding to the product ion spectra obtained by the searching; within the mass-to-charge ratio range of the obtained mass-to-charge ratio window, obtaining ion peaks from the product ion spectra obtained by the searching; and determining whether ions corresponding to the obtained ion peaks are precursor ions corresponding to the product ion spectra obtained by the searching.
