Abstract

The disclosure relates, in particular, to the operation of radio frequency (RF) ion guides which receive, intermediately store, separate according to a physical-chemical property, spatially translate and finally output gas-phase ions. RF ion guides according to the disclosure may be part of, or be coupled with, a mass analyzer. The disclosure serves to improve the space charge capacity of an RF ion guide, and to minimize fragmentation losses of ions contained in such RF ion guide over a wide range of masses and/or mobilities. The disclosure further serves to optimize the operational characteristics of an RF ion guide over a wide range of physical-chemical property values at minimal loss of ions due to fragmentation by RF ion heating.
