This volume reflects the changes that have taken place in the pharmaceutical industry over the last ten years, most notably the increased importance attached to the question of chirality, the growing influence of biotechnology and the need for more rigorous documentation and validation of analytical methods and procedures. The first part of this book deals with the application of new technology to pharmaceutical and biomedical analysis, reflecting the present needs for increased speed, sensitivity and selectivity in the analysis of drugs. The second chapter provides an overview of capillary electophoresis, which represents one of the most inportant analytical developments to impact directly on pharmaceutical development in recent years. Although not a chromatographic technique, capillary electrophoresis was considered too important to be ignored. Over the last 25 years, liquid chromatography has grown into a mature analytical technique and many of the fundamental issues concerned with retention and separation are well defined. The practitioners of modern liquid chromatography spend as much time in the development of techniques for sampling handling and automation as they do in the development of the separation. Therefore, Part Two of this book describes some of the recent advances in the areas of sample handling and the isolation of compounds from biological samples, including solid phase extraction, restricted access media for direct injection, coupled column technology and microdialysis. Similarily, Part Three contains two chapters concerned with liquid chromatographic methods for the isolation of drug substances, peptides and proteins from other complex media. The pharmaceutical industry and the process of drug development are highly regulated and the increasing importance that the regulatory authorities attach to validation has had a significant impact on the analytical techniques used for the analysis of drugs. Although this has increased the workload of analysts in the pharmaceutical industry, it has also improved the quality of analytical methods used in the support of investigational and new drug applications as well as the quality of methods published more recently in the literature. Consequently, Part Four of this volume describes approaches to the optimization and validation of liquid chromatography methods for the analysis of drugs in the bulk form, in pharmaceutical formulations and biological fluids.

For reasons both financial and environmental, there is a perpetual need to optimize the design and operating conditions of industrial process systems in order to improve their performance, energy efficiency, profitability, safety and reliability. However, with most chemical engineering application problems having many variables with complex inter-relationships, meeting these optimization objectives can be challenging. This is where Multi-Objective Optimization (MOO) is useful to find the optimal trade-offs among two or more conflicting objectives. This book provides an overview of the recent developments and applications of MOO for modeling, design and operation of chemical, petrochemical, pharmaceutical, energy and related processes. It then covers important theoretical and computational developments as well as specific applications such as metabolic reaction networks, chromatographic systems, CO2 emissions targeting for petroleum refining units, ecodesign of chemical processes, ethanol purification and cumene process design. Multi-Objective Optimization in Chemical Engineering: Developments and Applications is an invaluable resource for researchers and graduate students in chemical engineering as well as industrial practitioners and engineers involved in process design, modeling and optimization.

Pages : 408 pages

Recent years have seen a greater industrial emphasis in undergraduate and postgraduate courses in the pharmaceutical and chemical sciences. However, textbooks have been slow to adapt, leaving the field without a text/reference that is both instructional and practical in the industrial setting – until now. A Handbook of Bioanalysis and Drug Metabolismis a stimulating new text that examines the techniques, methodology, and theory of bioanalysis, pharmacokinetics, and metabolism from the perspective of scientists with extensive professional experience in drug discovery and development. These three areas of research help drug developers to optimize the active component within potential drugs thereby increasing their effectiveness, and to provide safety and efficacy information required by regulators when granting a drug license. Professionals with extensive experience in drug discovery and development as well as specialized knowledge of the individual topics contributed to each chapter to create a current and well-credentialed text. It covers topics such as high performance liquid chromatography, protein binding, pharmacokinetics and drug–drug interactions. The unique industrial perspective helps to reinforce theory and develop valuable analytical and interpreting skills. This text is an invaluable guide to students in courses such as pharmaceutical science, pharmacology, chemistry, physiology and toxicology, as well as professionals in the biotechnology industry.

Liquid Chromatography/Mass Spectrometry

This book is intended both to be an introduction to techniques and applications of liquid chromatography/mass spectrometry and to serve as a reference for future workers. When we undertook its writing, we chose not to cover the field, particularly applications, exhaustively. Rather we wished to produce a book that would be of use to people just beginning to use the technique as well as to more advanced practitioners. In this regard, we have sought to highlight techniques and applications that are of current importance, while not neglecting descriptions of approaches that may be of significance in the future. We hope that we have succeeded in this. At the same time we hope that the bibliography, with indexes classified by author and title, will make this book of value to those who may disagree with our emphasis. ACKNOWLEDGMENTS. One of us (C. G. E. ) wishes to acknowledge the en couragment of Professor J. A. McCloskey in undertaking this project. All four of us are grateful for the continuous and expert assistance of V. A. Edmonds in the preparation of the Bibliography. Alfred L. Y ergey Bethesda, Maryland Charles G. Edmonds Richland, Washington lvor A. S. Lewis London, England Marvin L.
