Title:
イオンガイド装置及びイオンガイド方法
Document Type and Number:
Japanese Patent JP6773237
Kind Code:
B2
Abstract:
An ion guiding device includes ring electrodes with a same size disposed in parallel; wherein a connection line of centers of the ring electrodes is defined as an axis, a normal of a plane where any of the ring electrodes is located and a tangent line of the axis at a center of the ring electrode form an included angle being a range of (0, 90) degrees; a radio-frequency voltage source, for applying an out-phase radio-frequency voltage on a neighboring ring electrode along the axis, so that ions are confined inside the ring electrode during a transmission process; and a direct-current voltage source, applying a direct-current voltage with an amplitude changing along the axis on the ring electrode, so that the ions are transmitted along the axis and focused to a position closer to an inner surface of the ring electrode along a direction of the normal.
