    Abstract: A method of processing multiple precursor ions in a tandem mass spectrometer includes generating a plurality of precursor ions with an ion source. At least some of the plurality of precursor ions is trapped in an ion trap. At least two precursor ions of interest are isolated from the plurality of precursor ions with a filtered noise field. Precursor ions of interest are sequentially ejected toward a collision cell. The sequentially ejected precursor ions of interest are fragmented in a collision cell. The mass-to-charge ratio spectra of the fragmented ions are then determined with a mass spectrometer.

    Abstract: A method for identifying a convolved peak is described. A plurality of spectra is obtained. A multivariate analysis technique is used to assign data points from the plurality of spectra to a plurality of groups. A peak is selected from the plurality of spectra. If the peak includes data points assigned to two or more groups of the plurality of groups, the peak is identified as a convolved peak. Principal component analysis is one multivariate analysis technique that is used to assign data points. A number of principal components are selected. A subset principal component space is created. A data point in the subset principal component space is selected. A vector is extended from the origin of the subset principal component space to the data point. One or more data points within a spatial angle around the vector are assigned to a group.
