Abstract
Official abstract text for this publication.
A method of mass spectral analysis in an analytical electrostatic trap ( 14 ) is disclosed. The electrostatic trap ( 14 ) defines an electrostatic field volume and includes trap electrodes having static and non-ramped potentials. The method comprises injecting a continuous ion beam into the electrostatic field volume.
First claim
Opening claim text (preview).
What is claimed is: 1. A method of mass spectral analysis in an analytical electrostatic trap, wherein the analytical electrostatic trap defines an electrostatic field volume and includes pairs of circular trap electrodes having substantially constant and non-ramped potentials, the method comprising: injecting a continuous ion beam into the electrostatic field volume of the analytical electrostatic trap for a period longer than at least 100 ion oscillations; isochronously oscill…
