A method of performing tandem mass spectrometry includes supplying a sample to a chromatography column, directing components included in the sample and eluting from the chromatography column to a mass spectrometer, acquiring a series of mass spectra including intensity values of ions produced from the components as a function of m/z of the ions, extracting, from the series of mass spectra, a plurality of detection points representing intensity as a function of time for a selected m/z, estimating, based on the plurality of detection points extracted from the series of mass spectra, a relative position of a selected detection point included in the plurality of detection points, and performing, at the mass spectrometer and based on the estimated relative position, a dependent acquisition for the selected m/z. The relative position of the selected detection point represents a position of the selected detection point relative to an expected reference point.
