Abstract:
A mass spectrometer system and a method of operating a mass spectrometer are provided. An RF field is produced between the plurality of rods to radially confine the ions in the rod set. The RF field has a resolving DC component field. The resolving DC component field is varied along at least a portion of a length of the rod set to provide a DC axial force acting on the ions.
