N2 - Amino acid/transition metal chloride mixtures were studied by plasma desorption mass spectrometry. The six aliphatic α‐amino acids were considered: glycine (Gly), alanine (Ala), valine (Val), leucine (Leu), isoleucine (Ile) and proline (Pro), together with four transition metal chloride salts: CoCl2, NiCl2, CuCl2 and FeCl2. Mixtures spectra show that MCat+ complexes are formed where M = amino acid and Cat = Co, Ni, Cu or FeCl. Fragmentations of MCat+ ions lead to both organometallic and organic ions. Isotopic labelling has allowed to demonstrate some fragmentation mechanisms.
