Title (EN) GAS FLOW ASSISTED ION TRANSFER SYSTEM WITH IMPROVED TRANSFER EFFICIENCY
(FR) SYSTÈME DE TRANSFERT IONIQUE ASSISTÉ PAR FLUX GAZEUX AEC UNE EFFICACITÉ DE TRANSFERT AMÉLIORÉE
Abstract:
(EN) An ion transfer system includes an ion source coupled to an ion inlet; an ion transfer tube assembly including a concentric ion transfer tube with a porous material that is permeable to a gas, the concentric ion transfer tube coupled to the ion inlet and the ion source, where a first gas that includes an ion stream flows through the concentric ion transfer tube; and a concentric gas tube, the concentric ion transfer tube disposed within the concentric gas tube, where a second gas flows between the concentric ion transfer tube and the concentric gas tube; an ion detection device coupled to a capillary tube that is coupled to the concentric ion transfer tube, where the capillary tube transports the ion stream to the ion detection device; and a pump coupled to at least one of the concentric ion transfer tube or the concentric gas tube.
(FR) Un système de transfert d'ions comprend une source d'ions couplée à une entrée d'ions; un ensemble tube de transfert d'ions comprenant un tube de transfert d'ions concentrique avec un matériau poreux qui est perméable à un gaz, le tube de transfert d'ions concentriques étant couplé à l'entrée d'ions et à la source d'ions, un premier gaz qui comprend un courant d'ions s'écoulant à travers le tube de transfert d'ions concentriques; et un tube de gaz concentrique, le tube de transfert d'ions concentriques étant disposé à l'intérieur du tube de gaz concentrique, où un second gaz s'écoulant entre le tube de transfert d'ions concentriques et le tube de gaz concentrique; un dispositif de détection d'ions couplé à un tube capillaire qui est couplé au tube de transfert d'ions concentrique, où le tube capillaire transportant le courant d'ions vers le dispositif de détection d'ions; et une pompe couplée au tube de transfert d'ions concentriques ou au tube de gaz concentrique.
