Determination of testosterone and related compounds in body fluids is of utmost importance in doping control and the diagnosis of many diseases. Capillary electromigration techniques are a relatively new approach for steroid research. Owing to their electrical neutrality, however, separation of steroids by capillary electromigration techniques requires the use of charged electrolyte additives that interact with the steroids either specifically or non-specifically. The analysis of testosterone and related steroids by non-specific micellar electrokinetic chromatography (MEKC) was investigated in this study. The partial filling (PF) technique was employed, being suitable for detection by both ultraviolet spectrophotometry (UV) and electrospray ionization mass spectrometry (ESI-MS). Efficient, quantitative PF-MEKC-UV methods for steroid standards were developed through the use of optimized pseudostationary phases comprising surfactants and cyclodextrins. PF-MEKC-UV proved to be a more sensitive, efficient and repeatable method for the steroids than PF-MEKC-ESI-MS. We discovered that in PF-MEKC analyses of electrically neutral steroids, ESI-MS interfacing sets significant limitations not only on the chemistry affecting the ionization and detection processes, but also on the separation. The new PF-MEKC-UV method was successfully employed in the determination of testosterone in male urine samples after microscale immunoaffinity solid-phase extraction (IA-SPE). The IA-SPE method, relying on specific interactions between testosterone and a recombinant anti-testosterone Fab fragment, is the first such method described for testosterone. Finally, new data for interactions between steroids and human and bovine serum albumins were obtained through the use of affinity capillary electrophoresis. A new algorithm for the calculation of association constants between proteins and neutral ligands is introduced.

It is difficult, if not impossible, to visualize pharmaceutical industry processes without appropriate analytical control, of which chromatographic and, more recently, capillary electromigration techniques constitute a considerable proportion. Problems such as deciding which separation technique will be the best, whether a chromatographic or an electrokinetically driven method is preferred, calibration procedures and method validation, identification of impurities by on-line hyphenation with techniques based on physicochemical principles other than chromatography and electrophoresis and assaying of basic physicochemical properties are all to be solved by the analytical chemist. Unintended errors can occur quite frequently. This volume covers all the above outlined areas, emphasizing those which the authors know from pharmaceutical research to cause problems in practice. The basic guidelines have been summarized along with the necessary theoretical background to help analysts select and apply modern chromatographic and electrokinetic methods of analysis in drug production and quality control and help them solve their particular problems.

What drives a scientist to edit a book on a speci c scienti c subject such as chiral mechanisms in separation methods? Until December 2005, the journal Analytical Chemistry of the American Chemical Society (Washington, DC) had an A-page section that was dedicated to simple and clear presentations of the most recent te- niques or the state of the art in a particular eld or topic. The “A-page” section was prepared for a broad audience of chemists including industrial professionals, s- dents as well as academics looking for information outside their eld of expertise. 1 Daniel W. Armstrong, one of the editors of this journal and a twenty-year+ long friend, invited me to present my view on chiral recognition mechanisms in a simple and clear way in an “A-page” article. In 2006, the “A-page” section was maintained as the rst articles at the beginning of each rst bi-monthly issue but the pagination was no longer page distinguished from the regular research articles published by the journal. During the time between the invitation and the submission, the A-page section was integrated into the rest of the journal and the article appeared as (2006) Anal Chem (78):2093–2099.

This book deals with chromatographic and electrophoretic methods applied for the separation (quantitation and identification) of biologically relevant compounds. It is assumed that the potential reader is familiar with the basics of chromatographic and electromigration methods. Individual separation modes are dealt with to an extent which follows their applicability for biomedical purposes: liquid chromatography and electromigration methods are therefore highlighted. Each chapter is completed with a list of recent literature covering the 1987-1997 period, which can be used for further guidance of the reader in his/her own field. The chapters have been written by specialists in a particular area and with an emphasis on applications to the biomedical field. This implies that theoretical and instrumental aspects are kept to a minimum which allows the reader to understand the text. Considerable attention is paid to method selection, detection and derivatization procedures and troubleshooting. The majority of examples given represent the analyses of typical naturally-occurring mixtures. Adequate attention is paid to the role of the biological matrix and sample pretreatment, and special attention is given to forensic, toxicological and clinical applications. The book is completed with an extensive Index of Compounds Separated.

With contributions from international experts, Chiral Separations by Capillary Electrophoresis provides a general overview of the principles of chiral separation by capillary electrophoresis and the different chiral selectors available. The book discusses the most important as well as several new chiral selectors used in capillary electrophoresis. It reviews recent pharmaceutical and biomedical applications and explores novel techniques, such as capillary electrophoresis coupled to mass spectrometry and microchip technology. The book also examines the quantitative aspects of capillary electrophoresis, the possibilities of capillary electrochromatography, and the various chiral columns available. Capillary electrophoresis has proven to be an effective tool for chiral separation. This book explains how this technique can be used in the separation of molecules, offering insight into both existing and emerging applications.

Wines from Grape Dehydration is the first of itskind in the field of grape dehydration - the controlled dryingprocess which produces a special group of wines. These types of wine are the most ancient, made in the Mediterraneanbasin, and are even described in Herodotus. Until few years ago, itwas thought that these wines – such as Pedro Ximenez, Tokai,Passito, and Vin Santo – were the result of simple grapedrying, because the grapes were left in the sun, or insidegreenhouses that had no controls over temperature, relativehumidity or ventilation. But Amarone wine, one of the most prizedwines in the world, is the first wine in which the drying is acontrolled process. This controlled process – grapedehydration – changes the grape at the biochemical level, andinvolves specialist vine management, postharvest technology andproduction processes, which are different from the typicalwine-making procedure. After a history of grape dehydration, the book is then divided intotwo sections; scientific and technical. The scientific section approaches the subjects of vineyardmanagement and dehydration technology and how they affect thebiochemistry and the quality compounds of grape; as well asvinification practices to preserve primary volatiles compounds andcolour of grape. The technical section is devoted to fourmain classes of wine: Amarone, Passito, Pedro Ximenez, andTokai. The book then covers sweet wines not made by grape dehydration, andthe analytical/sensorial characteristics of the wines. A concludingfinal chapter addresses the market for these specialwines. This book is intended for wineries and wine makers, wineoperators, postharvest specialists, vineyard managers/growers,enology/wine students, agriculture/viticulture faculties and courseleaders and food processing scientists
