Abstract
A mass spectrometer comprising an ion mobility separator for separating ions according to their ion mobility is disclosed. The ion mobility separator comprises a plurality of electrodes and one or more transient DC voltages or one or more transient DC voltage waveforms are progressively applied to the electrodes so that ions having a certain ion mobility are separated from other ions having different ion mobilities.
