Abstract
A method of operating a mass spectrometer comprising: detecting a first ion species using a first gain setting of a detector or a first emission current for a first mass-to-charge range; detecting a second ion species using a second gain setting of the detector or a second emission current for a second mass-to-charge range; and using the detected first and second ion species to calibrate the mass range of a mass analyzer of the mass spectrometer, to tune the resolution of the mass analyzer, or to tune an ion optic of the mass spectrometer.
