Bewitched is an odd word with which to begin a chemical textbook. Yet that is a fair description of how I reacted on first leaming of ion exchange and imagining what might be done with it. That initial fascination has not left me these many years later, and it has provided much ofthe motivation for writing this book. The perceived need for a text on the fundamentals of ion chromatography provided the rest. Many readers will have a general idea of what ion chromatography is and what it does. Briefly, for those who do not, it is an umbrella term for a variety of chromatographie methods for the rapid and sensitive analysis of mixtures of ionic species. It has become highly developed in the last decade, and while it is now routinely used for the determination of organic as weH as inorganic ions, its initial impact was greatest in the area of inorganic analysis. In the past the determination of inorganic ions, particularly anions, meant laborious, time-con suming, and often not very sensitive "wet chemieal" methods. In the last ten years that has changed radically as ion chromatography has supplanted these older methods.

The author describes the bases of the major separation and detection techniques of IC; discusses the problems presented by the disparate requirements of separation and detection; shows how these problems have been solved in a compatible and harmonious way; and brings out the relationship between the
