ABSTRACT:
A method for the mass-selective transport of ions, especially in a mass spectrometer, comprises the steps movement of the ions on a movement path on which a plurality of electrodes are arranged, and loading the electrodes with pulse-shaped acceleration voltages under the effect of which the ions experience a mass-dependent change of speed, wherein the electrodes are loaded with the pulse-shaped acceleration voltages such t at target ions with a pre-determined target mass are accelerated along the movement path Furthermore, an ion conductor for mass-selective transport of ions, especially in a mass spectrometer, is described.
