Description
This book provides a comprehensive discussion of the major aspects involved in elemental speciation. Sample preparation, separation techniques, instrumentation and quality assurance are all discussed. In addition, individual chapters are devoted to speciation of environmental samples and speciation of biological, clinical, and nutritional samples. Individual chapters are written by leaders in the field, and the book has been organized so that the reader may learn how to collect a sample and prepare it. Ways to separate and detect analytes of interest, and steps to take to ensure the validity of the measurements are also discussed. This book is unique in its comprehensive treatment of this subject.
