UHPLC in Life Sciences

Davy Guillarme gained his PhD 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 PhD 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.
