    摘要: The invention provides a method for acquiring a mass spectrum with a Fourier transform mass spectrometer, wherein analyte ions and additional reporter ions oscillate at mass specific frequencies in a measuring cell of the frequency mass spectrometer and interact by Coulomb forces; the image current signal induced by the reporter ion is measured; and mass signals of the analyte ions are determined from a sideband signal of the reporter ions in the frequency domain or from the instantaneous frequency of the reporter ions in the time domain.

    摘要: 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.
