ION GUIDING DEVICE AND RELATED METHOD

WIPO Patent Application WO/2019/003456

A1

The present invention provides an ion guiding device and an ion guiding method. The ion guiding device comprises a first electrode assembly, the first electrode assembly comprising two parallel electrode units arranged along a spatial axis; a second electrode assembly, the 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, so as to generate a DC electric field along the spatial axis to control the movement of ions. The ion guiding device and the ion guiding method of the present invention realize a curved ion guiding structure, and provide an electric field in both the axial direction and the radial direction.
