Claim Text:
1. A method of analyzing a sample comprising: performing an experiment including chromatographic separation and mass spectral analysis of the sample, wherein said mass spectral analysis includes alternating multiple times within a time scale of a single chromatographic peak between a low energy mode generating primarily precursor ions and a high energy mode generating primarily fragment ions; obtaining low energy spectra and high energy spectra from the experiment, the low energy spectra including primarily precursor ion data for the precursor ions obtained from the low energy mode, the high energy spectra including primarily fragment ion data for the fragment ions obtained from the high energy mode; determining characteristics for each of the precursor ions using the low energy spectra and each of the fragment ions using the high energy spectra, the characteristics including a chromatographic retention time and a peak profile; and determining a group of any of the precursor ions and the fragment ions having corresponding chromatographic retention times and corresponding peak profiles, said group denoting a portion of the precursor ions and the fragment ions deriving from a common originating molecule.
