Abstract: Techniques are described for matching a precursor ion with one or more related product ions, including providing a plurality of input data sets obtained from a plurality of injections, each of the plurality of input data sets including a same precursor ion and one or more product ions, normalizing the plurality of input data sets in accordance with a single retention time for the precursor ion, for each of the plurality of input data sets, determining which product ions are within a predetermined retention time window with respect to the single retention time for the precursor ion, and if a product ion is within the predetermined retention time window in at least one of the plurality of input data sets, determining that the product ion is related to the precursor ion having the single retention time

Abstract: The present disclosure relates generally to metabolomics and lipidomics, and to the analysis of metabolite and lipids in simple and complex mixtures. More specifically, the present disclosure relates to a mass spectrometry system using data independent acquisition and having quadrupole and ion mobility separation capabilities for the identification and quantification of metabolites and lipids. In some embodiments, an optional chromatographic separation can also be included.
