Reflecting the tremendous development of ion chromatography in recent years, the best-selling book by Fritz and Gjerde has now gone into a third edition. This is essentially a new book, describing materials, principles, and methods of ion chromatography in a clear and concise style. The book can be used both as an introduction for the new comer and as a practical guide for method development and applications for the experienced user. It contains handy tables with useful data, e. g. on detection and elution conditions. With this new edition, the scope has been enlarged to include capillary electrophoresis as well as chemical speciation. The readers of this book will profit from the authors' background and experience both in education and industrial application.
