Title:
ION MOBILITY SPECTROMETER
Document Type and Number:
WIPO Patent Application WO/2013/067366
Kind Code:
A4
Abstract:
A method and apparatus are disclosed for improving ion mobility spectrometry by using a fast and spatially wide ion gate based on local RF field barrier opposed to a switching DC field. The improvement accelerates the ion mobility analysis and improves charge throughput and dynamic range of the IMS. The invention is particularly suited for rapid dual gas chromatography. In one important embodiment, the accelerated IMS is coupled to a multi- reflecting time-of-flight mass spectrometer with a fast encoded orthogonal acceleration. There are described methods of comprehensive and orthogonal separation in multiple analytical dimensions.
