The purpose of this book is to collect into one volume the research done on the mass spectrometry of peptides. It balances a range of topics including theory, instrumentation, analytical techniques, and biological applications. The scope of the work contains three major sections: ionization methods, instrumental developments, and analysis of peptides. It describes 252Cf plasma desorption and laser-induced multiphoton ionization methodology. This exciting resource covers many new areas, including continuous flow FAB, quantification of human neuropeptides, and peptide mapping. It also discusses Q-FTMS, cross-links, and metal ions.
