Abstract
This invention presents a kind of ion guide device comprising multiple layers of stretched wire electrodes crossing in space. These wire electrodes are distributed along a defined ion guiding axis in the ion guide device. Each layer of wire electrodes contains at least two wire electrodes with some distance away from the guiding axis, and rotates with an angle relative to wire electrodes on neighboring layer. The ion guide contains multiple layers of wire electrodes to form a cage-like ion guide tunnel and keeps the mounting framework of those wire electrodes outside of the ion guide tunnel, thus reducing the interference of the gas flows from the ion guide device. A power supply provides voltage to each layer of wire electrodes, creates an electric field which focuses the ions towards the guiding axis.
