Abstract
Ions are separated from a sample over time and filtered. The precursor ions produced at each step are fragmented. Resulting product ions are analyzed using a mass analyzer, producing a product ion spectrum for each step of the transmission window and a plurality of product ion spectra for the mass range for the each scan. The plurality of product ion spectra are received, producing a plurality of multi-scan product ion spectra. At least one product ion is selected from the plurality of multi-scan product ion spectra that is present at least two or more times in product ion spectra from each of two or more scans. A known separation profile of a precursor ion is fit to intensities from the at least one product ion in the plurality of multi-scan product ion spectra to reconstruct a separation profile of a precursor ion of the at least one product ion.
