Title:
イオンの活性化及び貯蔵を強化するためのセグメント化リニアイオントラップ
Document Type and Number:
Japanese Patent JP6991424
Kind Code:
B2
Abstract:
A linear ion trap includes at least two discrete trapping regions for processing ions, a RF electrical potential generator, a multi-output DC electrical potential generator, and a control unit. The RF electrical potential generator produces two RF waveforms each applied to a pair of pole electrodes of the linear ion trap forming a RF trapping field component to trap ions radially. The multi-output DC electrical potential generator produces multiple DC field components superimposed to the RF field component and distributed across the length of the linear ion trap to control ions axially. The control unit switches the DC electrical potentials and corresponding DC field components collectively forming a first trapping region populated with ions to alter ion potential energy from a first level to a second level, and enables a first ion processing step in at least one of the first and second levels.
