"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."--Jacket.
