  • A new technique for high performance tandem time-of-flight mass spectrometry

    Creator:
    Katz, Daniel Louis
    Abstract:
    The main result of this written dissertation is a mathematical solution to the problem of multiplex recording for high performance tandem time-of-flight mass spectrometry. The prescription is to use a time-lag accelerator in the second stage to match the ion optical properties of the decay fragments to the requirements of...

  • 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...

  • Development of fragmentation techniques in mass spectrometry for biological applications

    Creator:
    Ji, Hong
    Abstract:
    In this dissertation, I present the work of developing more efficient and economical techniques for fragmenting large bio-molecules, and ultimately making mass spectrometry a more powerful tool in proteomics, DNA sequencing, and other areas of biomolecular analysis. Aiming at lowering the installation and operating cost, and delivering electron capture dissociation...
