The mass spectrometric analysis of salts can be carried out by dissolving the material of interest and polyethylene oxide 4000 (approx. 1:1) in water, applying the mixture to the emitter and introducing the latter into the field‐desorption source of a conventional mass spectrometer. After the application of 4 kV across the emitter, a negative‐ion mass spectrum can be recorded. The method has been applied to a considerable number of inorganic and organic salts.
