The device includes a multipole ion guide having a set of rods positioned along the longitudinal direction on an inscribed diameter equal to or less than 3.5 mm, a voltage source which provides alternating voltages to at least a subset of the rods to create a trapping field in a transverse direction, and a conductance limit having an opening d and placed at the exit of the multipole ion guide. At the end of this configuration near the opening of the conductance limit, a converging continuum gas flow through the conductance limit is provided that transfers the ions collimating near a center of the ion guide into a low gas pressure region. The method injects ions into the elevated gas pressure region of the ion guide, and transports the ions in the converging continuum gas flow into the low gas pressure region.

摘要： A method and apparatus for trapping ions in an ion trap having a ring electrode and a plurality of end-cap electrodes. Ions are introduced into a ion trap cavity of the ion trap from an external source or by desorption of a substance in the ion trap cavity. In a first embodiment, as the ions are introduced in the ion trap cavity, the amplitude of an RF voltage being applied to the ring electrode is gradually increased to trap the ions in the ion trap cavity. In a second embodiment, as the ions are introduced in the ion trap cavity, a retarding voltage is applied to the end-caps to reduce the initial kinetic energy of the ions. In a third embodiment, as the ions are introduced in the ion trap cavity from a probe tip inserted in the cavity, a retarding voltage is applied to the probe tip.
