Beschreibung

The only comprehensive guide to CIMS applications in structural elucidation and analytical studies

Chemical Ionization Mass Spectrometry, 2nd Edition, provides a comprehensive, up-to-date review of CIMS applications in structural elucidation and quantitative analytical studies. For the benefit of readers without a background in gaseous ion chemistry, a thorough review is presented in Chapter 2. Other chapters discuss such topics as reagent ion systems within the context of the thermochemistry and kinetics of the ionization process, including reactions and the type of information obtained; isotopic exchange reactions; stereochemical effects in chemical ionization; and reactive ion/molecule collisions in quadrupole cells. Chemical ionization mass spectra of 13 classes of compounds are discussed in detail to illustrate the influence of different functional groups on the spectra observed.

Chemical Ionization Mass Spectrometry, 2nd Edition will be a valuable reference for anyone interested in mass spectrometry and gaseous ion chemistry in general.
