Abstract
A method and apparatus of compensating a magnetic field inhomogeneity in a dynamically harmonized FT-ICR cell is presented, based on adding of extra electrodes into the cell, the extra electrodes being shaped in such a way that the averaged electric field created by these electrodes produces a counter force to the forces caused by the inhomogeneous magnetic field on the cycling ions.
