Ultrasound In Chemistry - Analytical Applications

This comprehensive reference and handbook covers all aspects of ultrasound for analytical applications. Besides classical extraction techniques, it also provides an overview of ultrasound applications and devotes two chapters to proteomics and polymer technology. From the contents: * Common ultrasonic devices * Elemental speciation * On-line applications * Accelerated extraction of semivolatile and volatile organics * Extracting reagent * The ultrasonic bath vs. the ultrasonic probe * Liquid-liquid extraction * Liquid-solid extraction * Solid-liquid extraction * Solid-phase extraction * Solid-phase microextraction * Stir bar sorptive extraction Of great interest to researchers in academia and industry, as well as analytical and natural products chemists, and those working in trace analysis.

J. L. Capelo-Martinez obtained his PhD in chemistry in 2002 from the University of Vigo, Spain, where he was associate professor from 1999 to 2002. In December 2004 he became Research Fellow at the Associated Laboratory REQUIMTE, as well as at the Chemistry Department of the New University of Lisbon, and in 2006 was invited as an auxiliary professor to the same institution. His research work is related to new uses of ultrasonic energy as a tool at the Analytical Chemistry Laboratory. Dr. Capelo has more than fifty manuscripts and several patents to his name, he is a regular referee for various analytical journals and a member of the advisory board of the Analytical Journal TALANTA.

"Analytical Applications is a practical book that emphasizes some of the latest developments in the implementation of ultrasound in the analytical lab." (Analytical and Bioanalytical Chemistry, August 2009)
