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.

Abstract: An ion mobility analyzer, combination device thereof, and ion mobility analysis method. The ion mobility analyzer comprises an electrode system that surrounds the analytical space and a power device that attaches to the electrode system an ion mobility electric potential field that moves along one space axis. During the process of analyzing mobility of ions to be measured, by always placing the ions to be measured in the moving ion mobility electric potential field, and keeping the movement direction of the ion mobility electric potential field consistent with the direction of the electric field on the ions to be measured within the ion mobility electric potential field, theoretically a mobility path of an infinite length can be formed so as to distinguish ions having mobility or ion cross sections that have very small differences.

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.

Abstract: An ion optical device includes one or more pairs of confinement electrode units arranged at two sides of a first direction; a power supply device for applying opposite radio-frequency voltages to the paired confinement electrode units respectively and forming thereon DC potentials distributed in a second direction orthogonal to the first direction to form a potential barrier herein over a length portion of the first direction; one first area and one second area positioned at two sides of the potential barrier in the second direction; and a control device connected with the power supply device for controlling an output thereof to change the potential barrier to manipulate the ions transported/stored in the first area being transferred to the second area through the potential barrier in ways based on the mass to charge ratio or mobility of the ions and continue being transported along the first direction.
