Abstract
There is provided a method of guiding ions, comprising providing an ion guide comprising a plurality of electrodes, confining ions radially within said ion guide by applying one or more voltages to said plurality of electrodes, applying an orthogonal DC field along at least a portion of said ion guide in order to control the temperature of ions as they travel through said ion guide, and applying an electrostatic driving potential to said plurality of electrodes to urge ions along the axial length of the ion guide, wherein said electrostatic driving potential is applied in the form of a DC travelling wave potential or other transient DC potential.
