Abstract
An ion mobility analyser comprising an ion guide is provided. The ion guide defines an ion drift channel extending in an axial direction an includes first and second electrode assemblies provided on opposing sides of the ion drift channel. Each of the first and second electrode assemblies extend in the axial direction and in a transverse direction which is transverse to the axial direction. The first and second electrode assemblies are spaced apart on opposing sides of the ion drift channel by a first distance at a narrowest point along the axial direction. Each of the first and second electrode assemblies comprises a set of first electrodes, and a set of second electrodes. The electrodes in the first and second sets are arranged in an alternating pattern in the transverse direction. The alternating pattern extends in the transverse direction a second distance that is greater than the first distance.
