Introducing the much-heralded new book that explains this revolutionary new analytical sample preparation procedure. Provides a theoretical basis for understanding microwave acid sampling requiring elemental or chemical analysis. Describes techniques and equipment found most effective. Gives direct practical applications of the methods to a variety of sample types. Covers most aspects of closed vessel microwave digestion and open vessel acid composition. Demonstrates fundamental relationships that can be used to predict the conditions that will occur under specific parameter settings. Addresses safety considerations for each technique demonstrated. This book is truly multidisciplinary: its techniques can be used in inorganic elemental analysis, sample digestion, food analysis, environmental sample preparation chemistry, and other areas.
