Clear, Practical Coverage of an Important Reemerging Technology Supercritical Fluid Extraction provides a clear, practical, step-by-step introduction to a sample preparation method that helps laboratories reduce or eliminate the use of halogenated solvents, extract samples more quickly and efficiently, and improve the accuracy of their results. By encouraging a deliberate, systematic approach to supercritical fluid extraction (SFE) methods and techniques, this book enables scientists and technicians to avoid disappointing results and erroneous conclusions and develop reliable guidelines for using this versatile technology. It demonstrates how to make the most of a process that is highly reproducible, fast, and quantitative at sub-ppb levels; preserves the chemical integrity of the analyte to be extracted; and yields a concentrated sample solution that can be easily manipulated. Topics covered include: Properties of supercritical fluids Functional group solubility in supercritical fluids Collection efficiency in off-line SFE Extraction strategies Applications of analytical SFE For analytical chemists, technicians, and laboratory managers, this book is the key to a technology that can make every sample extraction and analysis cleaner, more efficient, and more reliable.
