  • Data-dependent selection of dissociation type in a mass spectrometer
    Patent number: 8168943
    Abstract: Methods and apparatus for data-dependent mass spectrometric MS/MS or MSn analysis 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 MSn spectrum of the resultant product ions may be acquired.
