Abstract
A mass spectrometer is disclosed comprising a device which is operable in a first mode of operation to separate ions temporally according to their ion mobility by applying a continuous axial electric field. The device is also operable in a second mode of operation wherein ions are separated temporally according to the their mass to charge ratio by pulsing an applied axial electric field ON and OFF.
