ABSTRACT:
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.
