Abstract

The ion guiding device comprises a first electrode assembly comprising two parallel electrode units arranged along a spatial axis; a second electrode assembly comprising at least two non-parallel electrode units arranged in a plane between the parallel electrode units along the spatial axis, wherein a space enclosed by the first electrode assembly and second electrode assembly forms an ion transmission channel along the spatial axis; and, a power supply device, which is configured to apply RF voltages with different polarities to the first electrode assembly and the second electrode assembly to generate a RF electric field in the directions perpendicular to the spatial axis to confine ions, and separately apply DC voltages to the first electrode assembly and the second electrode assembly to generate a certain DC voltage difference, to generate a DC electric field along the spatial axis to control the movement of ions.
