Abstract[English]
An IMS device is provided that includes at least one surface, first and second pluralities of electrodes disposed on the surface, and an ion path having first and second accumulation regions and a separation region. The IMS device is configured to receive, guide, temporally separate, and discharge ions. Each accumulation region is configured to switch between accumulation and release states in which ions are accumulated and released therefrom, respectively. The separation region is positioned downstream of the first accumulation region and configured to temporally separate ions based on mobility. The first accumulation region is synchronized with a downstream mass filter while the second accumulation region is dependent upon the state of a gating element, which is positioned downstream of the IMS device and configured to control the flow of ions to a mass analyzer. A method in accordance with the foregoing is also provided.[French]
L'invention concerne un dispositif IMS qui comprend au moins une surface, des première et seconde pluralités d'électrodes disposées sur la surface, et un trajet d'ions ayant des première et seconde régions d'accumulation et une région de séparation. Le dispositif IMS est configuré pour recevoir, guider, séparer et décharger temporellement des ions. Chaque région d'accumulation est configurée pour commuter entre des états d'accumulation et de libération dans lesquels des ions sont accumulés et libérés de celles-ci, respectivement. La région de séparation est positionnée en aval de la première région d'accumulation et configurée pour séparer temporellement des ions sur la base de la mobilité. La première région d'accumulation est synchronisée avec un filtre de masse en aval tandis que la seconde région d'accumulation dépend de l'état d'un élément de déclenchement, qui est positionné en aval du dispositif IMS et configuré pour commander le flux d'ions vers un analyseur de masse. L'invention concerne également un procédé conforme à ce qui précède.
