ION TRAPS WITH QUADRATIC POTENTIALS IN FOURIER TRANSFORM BASED MASS SPECTROMETRY. HARMONIZED MULTI-ELECTRODE KINGDON TRAPS AND FT ICR CELL.

摘要

The review of current stage of development of the ion trap devices, which are using electric fields with quadratic dependence on coordinate and FT MS approach to signal detection and processing, will be given with emphasize on multiple electrode harmonized Kingdon traps[1] and dynamically harmonized FT ICR cells [2]. The general approach both analytical and digital to electric field calculation for such devices will be presented as well.
