In Fourier transform ion cyclotron resonance mass spectrometry, simultaneous storage of positive and negative ions is possible with double well potentials. Positive and negative ions are stored in different locations of the cell (nested trap). For experiments with ion/ion reactions, positive or negative ions have to share the same region of the cell. An approximation of the potential can be used to calculate how ions can be brought together. Field‐induced chaotic ion motion leads to total mixing of positive and negative ions in a suitable acceleration field. © 1997 John Wiley & Sons, Ltd.
