A switchable branched ion guide is disclosed. The switchable branched ion guide includes a trunk section, first and second branch sections, a junction connecting the trunk section to the branch sections, and a movable valve member located at the junction. The valve member may be moved between a first position in which ion travel is permitted between the trunk section and first branch section and is inhibited between the trunk section and the second branch section, and a second position in which ion travel is permitted between the trunk section and the second branch section and is inhibited between the trunk section and the first branch section. The branched ion guide may be utilized, for example, to controllably switch an ion stream between two destinations such as mass analyzers.
L'invention concerne un guide ionique ramifié orientable. Le guide ionique ramifié orientable contient une partie tronc, une première section ramification et une seconde section ramification, une jonction connectant la partie tronc aux parties ramifications, et un élément valve mobile situé au niveau de la jonction. L'élément valve peut être actionné entre une première position dans laquelle la circulation ionique est permise entre la partie tronc et la première partie ramification et est interdite entre la partie tronc et la seconde partie ramification, et une seconde position dans laquelle la circulation ionique est permise entre la partie tronc et la seconde partie ramification et est interdite entre la partie tronc et la première partie ramification. Le guide ionique ramifié peut être utilisé, par exemple, pour commuter de manière contrôlée un courant ionique entre deux destinations telles que des analyseurs de masse.
