ABSTRACT

A method for calibrating an ion trap mass spectrometer is disclosed. The method includes establishing an optimal phase and amplitude-m/z relationship by acquiring peak quality data at varying values of amplitude and phase. The resonant ejection voltage applied to the electrodes of the ion trap may then be controlled during analytical scans in accordance with the established relationship between m/z and resonant ejection voltage amplitude.
