A novel cell design has been developed by INL inventors for use in Fourier transform ion cyclotron resonance mass spectrometers (FT-ICR-MS or FTMS) that allows accurate isotope ratio measurements to be acquired by minimizing adverse ion motions common to traditional FMTS cell designs. The cell allows all ions, regardless of mass, to be excited to the same radius in throughout the cell. Because all of the ions are at the same radius, the measured abundances accurately reflect the number of each type of ion in the cell. In addition, the cell design allows for wider mass-to-charge ranges to be observed with the same trapping and excitation parameters.
