This book Handbook provides introductory information about the most widely used instrumental techniques and methods used in analytical chemistry and helps the reader determine which technique is most appropriate for their needs. This book/disk Handbook consists of an introduction and seven sections, each addressing a major area of chemical analysis (separation techniques, optical spectroscopic techniques-qualitative, optical spectroscopic techniques-quantitative, mass spectrometry, electrochemical techniques, microscopic and surface techniques, polymer and macromolecular techniques) and a floppy disk containing Technique Selection software. Each section consists of chapters describing the most commonly used instrumental techniques in the area of analysis. Each chapter presents basic information about a specific technique. The common format used for each chapter facilitates selection and comparison of techniques. Each chapter contains the following topics: 1) a summary page, 2) how it works, 3) what it does including current applications, 4) types of samples analyzed, practical economic information, 5) summary of the routine operational characteristics, and 6) references to more detailed information on the technique.
