A method for automatically identifying groups of related peaks generated in a chromatography-mass spectrometry experiment comprises automatically choosing a time window defining a region of interest for mass spectral data generated by the experiment; automatically constructing a plurality of extracted ion chromatograms (XICs) for mass spectral peaks observed within the region of interest; automatically detecting and characterizing chromatogram peaks within each XIC and automatically generating synthetic analytical fit peaks thereof; automatically discarding a subset of the synthetic analytical peaks which do not satisfy noise reduction rules; automatically performing a respective cross-correlation score calculation between each pair of synthetic analytical fit peaks; and automatically identifying groups of correlated peaks in at least one mass spectrum within the region of interest.
