The third edition of this highly successful and established handbook has been completely revised and considerably extended. The new edition consists of two volumes. Added chapters or sections cover - New and important applications of ion chromatography in the life sciences, e. g. the analysis of proteins, nucleic acids, amino acids or carbohydrates. - New instrumentation that meets the demand for miniaturisation and reduced analysis times. - Coupling of ion chromatography to mass-spectrometeric or inductively coupled plasma detectors - validation of ion-chromatographic methods (important for quality assurance) There is no other book available that could match the timeliness and comprehensiveness of information presented in this handbook. The author has played a major role in the development of ion chromatography and is working for the leading instrument manufacturer. He has also been appointed as visiting professor at the University of Innsbruck, one of the prominent centers of chromatography research in the world.
