Since its commercial introduction in 2004, UHPLC (Ultra-High Performance Liquid Chromatography) has begun to replace conventional HPLC in academia and industry and interest in this technique continues to grow. Both the increases in speed and resolution make this an attractive method; particularly to the life sciences and more than 1500 papers have been written on this strongly-evolving topic to date. This book provides a solid background on how to work with UHPLC and its application to the life sciences. The first part of the book covers the basics of this approach and the specifics of a UHPLC system, providing the reader with a solid background to working properly with such a system. The second part examines the application of UHPLC to the life sciences, with a focus on drug analysis strategies. UHPLC-MS, a key technique in pharmaceutical and toxicological analyses, is also examined in detail. The editors (Davy Guillarme and Jean-Luc Veuthey) were some of the earliest adopters of UHPLC and have published and lectured extensively on this topic. Between them they have brought together an excellent team of contributors from Europe and the United States, presenting a wealth of expertise and knowledge. This book is an essential handbook for anyone wishing to adopt an UHPLC system in either an academic or industrial setting and will benefit postgraduate students and experienced workers alike.

Giới thiệu về tác giả
Davy Guillarme gained his Ph D in analytical chemistry from the University of Lyon (France) in 2004. He is now lecturer at the School of Pharmaceutical Sciences, University of Geneva (Switzerland). He is working mainly on the development of new approaches to perform ultra-fast and high resolution separations in liquid chromatography. He is also interested in the coupling of these strategies with alternative detection modes, particularly mass spectrometry. Jean-Luc Veuthey obtained his Ph D in analytical chemistry from the University of Geneva (Switzerland) in 1987. He is now full professor at the School of Pharmaceutical Sciences, University of Geneva (Switzerland). His interests include the development of LC and CE hyphenated to several detection modes for the analysis of drugs and metabolites. Sample preparation and validation of the procedures are also particularly studied in his laboratory.
