Problems solved by technology

However, energetic neutral particles accompanying focused ions cannot be focused and their collisions create sample surface secondary ions from outside the analysis region, which reduces the spatial specificity of the analysis

Embodiment Construction

[0070] refer to figure 1 , the mass spectrometry system 100 includes an ion source 110 for producing ions from a sample during analysis; an ion transport assembly 120 (as known in the art, which may include, for example, one or more RF multipole ion guides, and / or electrostatic focusing lens and / or aperture, and / or deflector and / or capillary); electrostatic lens assembly 130; analyzer assembly 140; and electronic controller 150. Ion transport assembly 120 , electrostatic lens assembly 130 , and analyzer assembly 140 are housed in one or more vacuum chambers 155 . Analyzer assembly 140 includes detector 145 . During operation of system 100 , ion source 110 generates ions, which are transported by ion transport assembly 120 to electrostatic lens assembly 130 . Lens assembly 130 directs these ions to ion analyzer assembly 140 where the ions are treated as their mass-to-charge ratio (M / Z) by application of appropriate electric and / or magnetic fields in analyzer assembly 140. fu...

Abstract

A system includes an electrostatic lens positioned between a charged-particle source and a detector. The lens includes: a first electrode having a first aperture in the path and aligned with a first axis; a second electrode in the path between the first electrode and the charged-particle detector, the second electrode having a second aperture positioned in the path and aligned with a second axis parallel to the first axis and displaced from the first axis along a first direction; a third electrode in the path between the first electrode and the second electrode; and a potential generator coupled to the first, second, and third electrodes.; During operation, the potential generator applies first, second, and third potentials to the first, second, and third electrodes, respectively, so that the electrostatic lens directs a beam of charged particles from the charged-particle source propagating along the first axis to propagate along the second axis.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of Provisional Application No. 61 / 449,193, filed May 4, 2011, the entire contents of which are incorporated herein by reference. technical field [0003] The present invention relates to electrostatic lenses and systems including electrostatic lenses. Background technique [0004] Various applications involve transporting charged particles from one location to another. This is the case, for example, in the ion transport of quadrupole mass filters and other types of mass spectrometers, from the pulsed release of trapped ions from a multipole ion guide ion trap into the pulsed region of a time-of-flight (TOF) mass spectrometer. situation. Furthermore, there is a need to enable improved, finer, general focusing of charged particle beams. However, the delivery of selected ions is often accompanied by the simultaneous delivery of unwanted particles, which may include charged particles ...
