Abstract
The present teachings are directed to methods and systems for the selection of ions for subsequent ion fragmentation in the analysis of a sample. Rather than select the most intense subset of precursor ions for further analysis in an attempt to maximize the number of high quality, identifiable MS/MS spectra, in some settings, systems and methods for analyzing and 5 identifying precursor ions for further processing can benefit from a discovery approach in which precursor ions are selected randomly/stochastically.
