Abstract
An ion separation device comprising a plurality of electrodes arranged in a two-dimensional grid, a gas supply configured to provide a gas flow along the first direction, and an ion inlet arranged to receive ions. The plurality of electrodes is configured to create one or more pseudopotential barriers of increasing magnitude along a first direction. A drag force is applied to the ions by the gas flow is opposed by a pseudopotential gradient of the plurality of electrodes.
