New trends in solid-phase extraction for analytical use-a practical introduction.Owing to its low cost, ease of use, and nonpolluting means of preparing samples for analysis, solid-phase extraction (SPE) is fast overtaking traditional liquid-liquid methods in clinical, pharmaceutical, agricultural, and industrial applications. This book describes what analytical scientists and technicians need to know about this emerging procedure: how it works, how to choose from available techniques, how to utilize it effectively in the laboratory. Along with the historical perspective and fundamental principles, this practical book reviews the latest literature on solid-phase materials, equipment, and applications-including EPA-endorsed techniques. Special features include:* Coverage of separation and uptake methods.* Promising developments in the use of membrane disks.* The advantages of using polymeric resins over silica materials.* Mechanism and use of ion-exchange materials for SPE.* A remarkably complete chapter on the extraction of metal ions.* Groundbreaking research in the miniaturized SPE technique.Readers seeking additional information on SPE procedures may wish to consult: SOLID-PHASE EXTRACTION, Principles and Practice, E.

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.

This completely revised and updated fourth edition of the best-selling classic is a thorough treatment of the subject while remaining concise and readable. New additions include capillary electrophoresis, monolithic columns, zwitterion colums, DNA/RNA analysis, fundamentals of the science of IC, and micro methods. The whole is rounded off by handy tables with details on detection or elution conditions, among others.
