Document Type and Number:
Japanese Patent JP7018525
Kind Code:
B2
Abstract:
The present invention relates to an ion guide for transferring ions to a mass spectrometer. The ion guide of the present invention is characterized in that a plurality of DC rings and a plurality of RF multi-pole rings with a plurality of electrodes are arranged so as to intersect with each other between an inlet into which the ions move and an outlet for transferring the ions, wherein the inner diameter of the DC rings is kept constant and the inner diameter of the RF multi-pole rings gradually decreases in a direction from the inlet to the outlet.
