Abstract
An ion guide generates a first RF field of Nth order where N is an integer equal to or greater than 2, and a second RF field of 2Nth order superimposed on the first RF field. The first and second RF fields may be generated by respective first and second sets of electrodes. Another ion guide may include a converging entrance section followed by an exit section. The converging section may have a hyperbolic profile. A hyperbolic profile may be presented by electrodes having a twisted configuration relative to an ion guide axis.
