Abstract
Mass spectra are received over time for a compound of interest. A primary XIC is calculated for a primary product ion of the compound and a secondary XIC is calculated for a secondary product ion from the mass spectra. A primary value is calculated from a combination of intensities of one or more points corresponding to one or more times of a primary peak of the primary XIC and a secondary value is calculated from a combination of intensities of one or more points corresponding to the one or more times of a secondary peak of the secondary XIC. Or, the primary value is calculated as an area of a time window within the primary peak and the secondary value is calculated as an area of the time window within the secondary peak. A ratio is calculated from the primary value and the secondary value.
