A new ionization technique: A radio-frequency signal was used to ionize neutral organic molecules in the ultrahigh-vacuum region of a Fourier transform ion cyclotron resonance mass spectrometer. Radio-frequency ionization (RFI) yielded signal/noise (S/N) ratios roughly six times higher than those generated by conventional 70 eV electron impact ionization (EI).
