Abstract
Curved rf multipole ion guides or angled linear rf multipole ion guides are designed to be rotatable or shiftable. Thus, the direction of guided ions can be altered by rotating or shifting these ion guides. In a mass spectrometer equipped with a multitude of ion sources, this allows to switch between ion sources without venting the vacuum system.
