Title:
積層リングイオンガイドに結合された動電又は静電レンズ
Document Type and Number:
Japanese Patent JP5410533
Kind Code:
B2
Abstract:
A device for improved transportation and focusing of ions in a low vacuum or atmospheric-pressure region of a mass spectrometer is constructed from one or more electro-dynamic or electrostatic focusing lenses that is/are coupled to the first electrode of a stacked ring ion guide (SRIG) to which oscillatory (e.g., radio-frequency) voltages are applied. Such configurations as disclosed herein, minimizes deleterious field effects and/or repositioning problems of desired ion transfer instruments that utilize such stacked ring ion guides by generally configuring the outlet end of the ion transfer device to a desired position within the electro-dynamic or electro-static focusing lens(es).
