A method/apparatus for multiplexing plural ion beams to a mass spectrometer. At least two ion sources are provided with means of transporting the ions from the ion sources to separate two-dimensional ion traps. Each ion trap is used for storage and transmission of the ions and operates between the ion sources and the mass analyzer. Each ion trap has a set of equally spaced, parallel multipode rods, as well as entrance and exit sections into which and from which ions enter and exit the trap, respectively. For each ion trap, the entrance section is placed in a region where background has pressure is at viscous flow. The pressure at the exit section drops to molecular flow pressure regimes without a break in the structure of the ion trap. Each trap alternately stores and transmits ions by way of a fast voltage switch applied to the ion trap exit lens.

L'invention concerne un procédé et un dispositif pour le multiplexage de plusieurs faisceaux ioniques vers un spectromètre de masse. Au moins deux sources ioniques sont prévues, avec un système de transport ionique depuis ces sources vers des pièges ioniques 2D distincts. Chaque piège permet la collecte et la transmission des ions et est opérationnel entre les sources et l'analyseur de masse. Chaque piège comporte une série de tiges multipode parallèles espacées par des intervalles identiques, ainsi que des parties d'entrée et de sortie des ions, respectivement. Pour chaque piège, la partie d'entrée se trouve dans une zone où la pression de base de gaz est au flux visqueux. La pression à la partie de sortie s'abaisse aux régimes de pression de flux moléculaire sans rupture dans la structure du piège. Chaque piège, alternativement, assure la collecte et la transmission des ions par commutation de tension rapide appliquée à la lentille de sortie du piège.
