Herein, we present the theoretical and experimental study of the recently introduced FTICR cell designs. We developed an approach that determines the electric field inside the cell, based on the measurement of calibration coefficients as a function of post-excitation radius and other conditions. Using the radial electric field divided by radius (E(r)/r) as a criterion of the cell harmonization, we compare the compensated cell approach with alternative designs and discuss practical implications of the cell compensation.
