Abstract:
The disclosure relates to methods and apparatus for ion separation, for example using time of flight and ion mobility spectrometry. Ion shutters for use in IMS cells and to methods of operating them are also disclosed. The shutter includes a first shutter electrode and a second shutter electrode. A barrier voltage between these two electrodes is controlled to open and close the shutter to allow ions of interest to pass through the shutter in a drift direction. The control involves varying both: (a) the voltage of the first shutter electrode; and (b) the voltage of the second shutter electrode.

Claim (Index 17):
The IMS cell of  claim 16  wherein the first shutter voltage provider and the second shutter voltage provider are configured to reset the shutter by changing the second shutter electrode voltage to increase the barrier voltage before returning the first shutter electrode voltage to the profile voltage.
