Abstract
A method of calibrating a mass spectrometer comprises generating calibration ions from an ion source that are transported from the ion source to a mass analyser of the mass spectrometer via an ion optics device. A characteristic voltage is applied to the ion optics device to control the transit of ions into or out of the ion optics device. The applied characteristic voltage results in an amount of unintentional dissociation of the calibration ions. An MS1 analysis of the calibration ions is performed using the mass analyser to obtain an MS1 spectrum. The amount of unintentional dissociation of the calibration ions in the MS1 spectrum is determined. The characteristic voltage is calibrated based on the amount of unintentional dissociation of the calibration ions to provide a target amount of unintentional dissociation during an MS1 analysis.
