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 12):
An IMS cell comprising:\n an ion shutter comprising a first shutter electrode and a second shutter electrode; a first shutter voltage provider configured to vary the first shutter electrode voltage; and a second shutter voltage provider configured to vary the second shutter electrode voltage, wherein the first shutter voltage provider and the second shutter voltage provider are configured to control a barrier voltage between the first shutter electrode and the second shutter electrode by varying both the first shutter electrode voltage and the second shutter electrode voltage thereby to control the passage of ions of interest through the shutter in a drift direction.
