Abstract
Methods and apparatus for data-dependent mass spectrometric MS/MS or MSanalysis are disclosed. The methods may include determination of the charge state of an ion species of interest, followed by automated selection of a dissociation type (e.g., CAD, ETD, or ETD followed by a non-dissociative charge reduction or collisional activation) based at least partially on the determined charge state. The ion species of interest is then dissociated in accordance with the selected dissociation type, and an MS/MS or MSspectrum of the resultant product ions may be acquired.
