Title:
ION TRAP WITH RADIAL OPENING IN RING ELECTRODE
Document Type and Number:
WIPO Patent Application WO/2014/144667
Kind Code:
A3
Abstract:
Apparatuses and methods for performing mass analysis are disclosed. One such apparatus may include an ion trap device. The ion trap device may comprise a first end cap having a first aperture and a second end cap having a second aperture, wherein the first aperture and the second aperture may define an ejection axis. The ion trap device may also comprise a ring electrode substantially coaxially aligned between the first and second end caps. The ring electrode may include an opening extending along a radial direction of the ring electrode, wherein the radial direction is substantially perpendicular to the ejection axis. One such method may include ionizing a sample in an ion trap through an opening separating at least part of first and second ring sections of the ion trap and detecting ions ejected though an aperture on an end cap of the ion trap.
