Many fundamental aspects of the methods used in mass spectrometry are here presented by outstanding scientists, with reference to very recent developments. The principles and applications of electrospray, ion spray and MALDI ionization technique are presented, together with optimised GC/MS interfacing systems and tools for quantitative analysis. A comprehensive treatment of modern instrumentation for mass analysis and detection is also included. The major part of the book deals with bioanalytical applications to peptides, proteins, oligonucleotides, polysaccharides, lipids and plant metabolites. Several papers are devoted to the evaluation of adduct formation between DNA and carcinogens. Environmental applications are also included, with examples of some specific cases.
Fundamentals and applications are treated with the same degree of depth: the first two parts of the book therefore provide a basis for the understanding of the biomolecular applications section.
Audience: Ideal for advanced graduate students of chemistry who have learned some basic mass spectrometry. Also useful for Ph.D. students in chemistry, biology and medicine. Of value to researchers in academic and industrial laboratories.
