Radio-Frequency Ionization of Organic Compounds for Mass Spectrometry Analysis

Angewandte Chemie (International ed. in English) | 1 Feb 2013

B Zekavat and T Solouki
Abstract
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 S/N ratios roughly six times higher than those generated by the conventional 70 eV electron impact ionization (EI).
