Problems solved by technology

[0005] There are at least several obvious disadvantages to this series-structured device
First, the operations that can be performed are restricted to the specific order in which the devices are arranged
Second, two different units are always required, thus increasing the complexity, size and cost of the overall system
Third, when ions are moved from one device to another in order to perform different operations, there is usually some loss of ions

Abstract

A set of electrodes to which different potentials are applied at different time periods to perform ion mobility-based spectroscopy and mass spectrometry (MS) on an ion sample by performing any number of ion mobility-based Spectroscopy and mass spectrometry to process ions and are performed as separate or overlapping steps to capture, separate and analyze charged particles and charged particles originating from atoms, molecules, particles, subatomic particles and ions.

Description

[0001] Cross References to Related Applications [0002] This document claims priority from Provisional Patent Application Serial No. 60 / 480052 filed June 20, 2003, the subject matter of which is incorporated herein by reference. technical field [0003] The present invention generally relates to ion storage, separation and analysis based on ion mobility and mass-to-charge ratio of charged particles and charged particles originating from atoms, molecules, particles, subatomic particles and ions in the same device. In particular, the present invention relates to a single device enabling ion trap mass spectrometry (ITMS) and ion mobility spectrometry, such as Intense Field Asymmetric Ion Mobility Spectroscopy or FAIMS, to be performed in any order in a single device, Differential mobility, lateral flow ion mobility spectrometry, thus performs two types of separations where at least two chemically specific discriminators with unique differences are available to provide identifica...
