Akronnal (M + 1)/M ratios in the lon trap mass spectrometer were examlned to resolve questions about their source. Compounds showlng minimal fragmentation provlde normal (M + 1)/M ratios except undar conditions of space charglng (high ion concentration). Substances provlding abundant alkyl Ions form (M + H)’ Ions through proton transfer to neutrals. Concentrations causing thls effect In the Ion trap mass spectrometer and the sources of the proton In the case of methyl decanoate are dlscussed.
