Abstract: Disclosed herein is an ion guide comprising a plurality of axially stacked plates, wherein at least some or all of said plates comprise: a first electrically conductive portion; and a second electrically conductive portion, wherein the second electrically conductive portion is electrically isolated from the first electrically conductive portion, the first and second electrically conductive portions being shaped and arranged relative to each other so as to define an opening through which ions are axially transmitted in use; wherein, in use, a first AC or RF voltage is applied to the first electrically conductive portion and a second AC or RF voltage is applied to the second electrically conductive portion in order to confine ions radially within said opening. The first and second electrically conductive portions (1, 2) may be separately formed and interleaved within the ion guide to define the plates. Alternatively the first (41, 43) and second (42, 44) electrically conductive portions may be printed onto a common substrate (4).
