Cell geometry considerations for the Fourier transform ion cyclotron resonance mass spectrometry remeasurement experiment.

Journal Article

Three cell geometries, closed cubic, closed elongated, and open elongated, are evaluated for optimum remeasurement performance in the Fourier transform ion cyclotron resonance mass spectrometry (FTICR) experiment. The advantages and disadvantages of each cell during normal FTICR operation are discussed. Unit remeasurement efficiency is obtained for the closed elongated cell at approximately 71% of the cell radius, whereas the open elongated cell achieves unit remeasurement at only approximately 18% of the cell radius. The closed cubic cell does not achieve unit remeasurement efficiency at a detectable signal level. A correlation between remeasurement efficiency and the characteristic radial electric field of each trapped ion cell is established. Radial dispersion of the ion cloud is considered the dominant signal loss mechanism in the remeasurement experiment, and cell geometries are examined for optimized sensitivity and unit remeasurement efficiency.
