Abstract
The invention relates to the selection of the most favorable ion species for the acquisition of fragment ion mass spectra when the ionization creates biopolymers in different charge states. The invention proposes a particularly fast method of selecting the most favorable parent ions for fragmentation of the different biopolymers from mass spectra, where the ionization is by electrospray ionization (ESI) or other ionization methods which produce similarly diverse charge states and which, for each biopolymer, contain many signal patterns of ions of the different charge states and different isotopic compositions. The selection is carried out in such a way that it does not measure more than one ion species from one biopolymer. Moreover, the most favorable filter pass-band width for isolating an ion species for fragmentation can be stated in each case.
