Embodiment Construction

[0087] In various embodiments, a stretched length ion trap (SLIT) is provided for use, eg, as a mass analyzer in a mass spectrometry device. The ion trap is characterized in that its trapping region is miniaturized in two dimensions, but stretched or elongated in a third dimension.

[0088] For example, Figure 1A-Figure 1E A view of a microelectrode device 100 for trapping charged particles is shown. Figure 1A is a perspective view. Figure 1B is a second perspective view at an alternate angle. Figure 1C is a top-down view. Figure 1D is a side sectional view along plane AA'. Figure 1E is a perspective sectional view along plane AA'.

[0089] The microelectrode device 100 includes three electrodes stacked in a longitudinal direction (z-direction as shown in the figure). These electrodes include a first end cap electrode 102 , a center electrode 104 and a second end cap electrode 106 . The center electrode 104 includes an elongated aperture 108 . The aperture 108 ex...

Abstract

A miniature electrode apparatus is disclosed for trapping charged particles, the apparatus including, along a longitudinal direction: a first end cap electrode; a central electrode having an aperture; and a second end cap electrode. The aperture is elongated in the lateral plane and extends through the central electrode along the longitudinal direction and the central electrode surrounds the aperture in a lateral plane perpendicular to the longitudinal direction to define a transverse cavity for trapping charged particles.
