  • Gas-phase fragmentation chemistry of protonated peptide ions

    Creator:
    Bythell, Benjamin James
    Abstract:
    The fragmentation characteristics of protonated peptides have been investigated using tandem mass spectrometry (MS/MS) under various fragmentation regimes and detailed density functional theory (DFT) reaction pathway calculations. The DFT calculations predict novel salt-bridge stabilized transition structures as well as consecutive reactions occurring in proton-bound dimers for some of the ions...

  • Ion pairing of nucleotides with surfactants for enhanced sensitivity in liquid matrix assisted secondary ion mass spectrometry

    Creator:
    Pavlovich, James Gilbert
    Abstract:
    In particle induced desorption-ionization mass spectrometry the strength of an analyte's signal under a given set of bombardment conditions is usually considered to be representative of the analytes relative surface activity. This rationale is generally used to explain differences in the technique's sensitivity between and within various classes of compound....
