Abstract
A method of mass spectrometry is disclosed comprising: performing a survey scan of a plurality of different types of parent or precursor ions, wherein the survey scan comprises analyzing the ion mobilities of the ions and mass analyzing the ions; determining the charge states of parent or precursor ions analyzed in the survey scan based on their determined combinations of ion mobility and mass to charge ratio; selecting a parent or precursor ion for fragmentation or reaction; and fragmenting or reacting the selected ion, wherein the fragmentation or reaction conditions are selected from a plurality of different fragmentation or reaction conditions based upon the determined charge state of the selected ion.
