1. A method of enabling data-dependent acquisition in a mass spectrometer, comprising:

  • obtaining a plurality of mass spectra from a sample;

    selecting from said plurality of mass spectra, a set of eluting m/z peaks of interest from a weighted mass spectrum by way of a correlation technique;

    obtaining phase data resulting from portions of extracted ion chromatographs (XIC) from said selected set of eluting m/z peaks of interests so that a subset of said set of eluting m/z peaks of interest can be identified; and

    triggering off of said identified subset of said eluting m/z peaks of interest based on said obtained phase data so that real-time data is acquired that corresponds to one or more eluting m/z peaks of interest.
