Fast atom bombardment (FAB) mass spectrometry: a mass spectral investigation of some of the insulins

Mass measurements of the protonated molecules [M + H]+ of four insulins are presented. In addition, structurally significant fragment ions are observed in the mass spectrum and metastable scanning has been used to link these ions to the protonated molecule.
