Notes:
Mass spectra of various involatile organic compounds, obtained by surface analysis with a laser microprobe mass analyser are reported. Metal-cationized quasimolecular ions of adenine, adenosine, 5-adenylic acid and sucrose supported on metal foils were observed. Metal attachment can also be detected from mixtures of metal salts and the organic compounds. Silver-cationized sugar molecules and atomic silver ions solvated by (H2O)x and (NH3)x (x = 1,2) have been found. The mass spectra are compared with those obtained by secondary ion mass spectrometry and similar techniques, discussing the processes of ion generation involved.
