The latest edition of a highly successful textbook, Mass
Spectrometry, Third Edition provides students with a complete
overview of the principles, theories and key applications of modern
mass spectrometry. All instrumental aspects of mass spectrometry
are clearly and concisely described: sources, analysers and
detectors. Tandem mass spectrometry is introduced early on and then
developed in more detail in a later chapter. Emphasis is placed
throughout the text on optimal utilisation conditions. Various
fragmentation patterns are described together with analytical
information that derives from the mass spectra.
This new edition has been thoroughly revised and updated and has
been redesigned to give the book a more contemporary look. As with
previous editions it contains numerous examples, references and a
series of exercises of increasing difficulty to encourage student
understanding. Updates include: Increased coverage of MALDI and
ESI, more detailed description of time of flight spectrometers, new
material on isotope ratio mass spectrometry, and an expanded range
of applications.
Mass Spectrometry, Third Edition is an invaluable
resource for all undergraduate and postgraduate students using this
technique in departments of chemistry, biochemistry, medicine,
pharmacology, agriculture, material science and food science. It is
also of interest for researchers looking for an overview of the
latest techniques and developments.
