1. A device for manipulating charged particles, the device comprising:

  • a series of electrodes arranged so as to form a channel for transportation of the charged particles;

    a power supply unit adapted to provide supply voltages to said electrodes so as to create a non-uniform high-frequency electric field within said channel, the pseudopotential of said field having two or more local maxima along the length of said channel for transportation of charged particles, at least within a certain interval of time, wherein transportation of the charged particles along the length of the channel is provided by transposition of the at least two of said maxima of the pseudopotential such that the at least two of said maxima are caused to travel with time along the channel, at least within a certain interval of time and at least within a part of the length of the channel, wherein the supply voltages are high-frequency voltages;

    wherein the said channel for transportation of the charged particles contains a gaswherein the gas pressure defines viscous flow conditions;

    wherein the pressure of the gas meets the condition λ

    /L<

    0.01, where L is a width of the transport channel and λ

    is the mean free path of molecules of said viscous gas.
