Abstract
A method of mass spectrometry is disclosed comprising detecting the ions transmitted by a mass filter () with a detector (); changing the RF and/or DC voltage applied to the mass filter () during a voltage transition period so as to change the mass to charge ratio capable of being transmitted by the mass filter (); preventing ions from reaching the detector during the voltage transition period; and allowing ions to be transmitted to the detector () after the voltage transition period.
