Abstract
A mass spectrum is generated by a process in which, from a mass scan signal comprising original samples defining a peak, a subset of the original samples defining the peak is selected. One or more synthesized samples are synthesized from the subset of the original samples. The one or more synthesized samples provide a temporal resolution greater than the temporal resolution of the original samples. The one or more synthesized samples are summed with respective temporally-aligned accumulated samples to produce the mass spectrum. The accumulated samples are obtained from mass scan signals generated during respective previously-performed mass scan operations.
