ABSTRACT:
A device (6) for separating ions according to differences in their ion mobility as a function of electric field strength is disclosed. The device (6) comprises an upper electrode (7a), a lower electrode (7b) and a plurality of intermediate electrodes (8). An asymmetric voltage waveform is applied to the upper electrode (7a) and a DC compensating voltage is applied to the lower electrode (7b).
