A device and method of manufacturing a device, such as an ion guide 7a, ion mobility or ion collision cell, is disclosed comprising one or more layers of intermediate planar, plate or mesh electrodes 2. A first array of first electrodes 8a-8e is provided on a first side of the intermediate layers and a plate electrode or a second array of second electrodes 9a-9e is arranged on the other side of the intermediate layers. An ion transmission region is formed within the ion guide 7a. One or more transient DC voltages or potentials may be applied to the first and second array of second electrodes 8a-8e, 9a-9e in order to urge, propel, force or accelerate ions through or along the ion guide 7a. |
