Untersuchung eines neuartigen elektromagnetischen Ionenkäfigs für Ion/Elektronreaktionen in der Gasphase mit FT-ICR-Massenspektrometrie

In icr, ion/electron reactions demand simultanious trapping of positive ions and electrons. A multisection cell with six trapping electrodes was investigated, wich can provide trapping potentials suitable for simultaneous trapping. for reaction, trapping potentials are changed with time so that potential wells for positive ions and electrons overlap. A reaction sequence of different trapping potentials for ion/electron and ion/ion reactions was developed and tested with singly and doubly charged xenon ions, and electrons.
