A mass spectrometer comprising an ion mobility separator 1 for separating ions according to their ion mobility is disclosed. The ion mobility separator 1 comprises a plurality of electrodes 3 and one or more transient DC voltages or one or more transient DC voltage waveforms are progressively applied to the electrodes 3 so that ions having a certain ion mobility are separated from other ions having different ion mobilities.
