Abstract
The experimental Fourier transform ion cyclotron resonance (FT/ICR) frequency range has been extended to 107 MHz. We report the observation of FT/ICR signals from electron-ionized species of mass-to-charge ratio 8, 7, 6, 5, 4, 3, 2, and 1 μ per elementary charge. We show that moderately high charge states of atomic ions (e.g., N(3+)) are easily generated and detected. Several applications for high-frequency FT/ICR mass spectrometry are proposed and discussed.
