Abstract
Calibration of a mass spectrometer is described. In one aspect, a mass spectrometer can generate an offset value indicative of the mass difference between the corrected and reference external calibrant ion data. By comparing the offset value to a threshold, a preliminary mass calibration can be modified, or a recalibration of the mass spectrometer is performed.
