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 26):
An ion shutter for an IMS cell, comprising a first shutter electrode and a second shutter electrode, each of the first and second shutter electrodes comprising elongate conductive elements, wherein the first shutter electrode is spaced apart from the second shutter electrode in a drift direction of the IMS cell and the elongate conductive elements of the first shutter electrode are aligned with those of the second shutter electrode in the drift direction.
