Abstract
The disclosure relates to an ion guiding device, including two sets of electrodes extending along a certain space axis, a first power supply device and a second power supply device. The electrodes are expandably arranged along a direction perpendicular to the space axis, at least one surface of each electrode in each set of electrodes is substantially on the same space plane, and the space planes for each set of electrodes are not same and not parallel, thereby forming an ion transmission channel having the cross sectional area gradually reduced in a direction perpendicular to the space axis; the first power supply device is used for applying radio-frequency voltages on at least a part of electrodes in the two sets of electrodes; and the second power supply device is used for applying voltage signals on at least a part of electrodes in the two sets of electrodes.
