This monograph addresses some questions that concern researchers in separation science, including: what is the current state of the art in liquid chromatography; has the development of liquid chromatography plateaued; if so, what new methods will take its place or complement it; and if not, where will the new frontiers be and what direction will liquid chromatography take? 1989 (0 471-84506-X) 688 pp. Quantitative Structure-Chromatographic Retention Relationships R. Kaliszan Written by a pioneer in the field, this book extends and updates research on quantitative structure retention relationships by consolidating and critically reviewing the extensive literature on the subject, while also providing the basic theoretical and practical information required in all investigations involving chromatography, analytical chemistry, biochemistry, and pharmaceutical research. Among the topics covered are the nature of chromatographic interactions, molecular interpretation of distribution processes in chromatography, topological indices as retention descriptors, and multiparameter structure-chromatographic retention relationships. 1987 (0 471-85983-4) 303 pp. Detectors for Liquid Chromatography Edited by Edward S.

Available in PDF, EPUB and Kindle. Book excerpt: This is the first detailed description of method development in chromatography - the overall process of which may be summarized as: method selection, phase selection, selectivity optimization, and system optimization. All four aspects receive attention in this book. Chapter 1 gives a short introduction, describes chromatographic theory and nomenclature, and outlines the method development process. Chapter 2 describes guidelines for method selection, and quantitative concepts for characterizing and classifying chromatographic phases. Selective separation methods, from both gas and liquid chromatography are given in Chapter 3; the main parameters of each method are identified and simple, quantitative relations are sought to describe their effects. Criteria by which to judge the quality of separation are discussed in Chapter 4 with clear recommendations for different situations. The specific problems involved in the optimization of chromatographic selectivity are explained in Chapter 5. Optimization procedures, illustrated by examples, are extensively described and compared on the basis of a number of criteria. Suggestions are made both for the application of different procedures and for further research. The optimization of programmed analysis receives special attention in Chapter 6, and the last chapter summarizes the optimization of the chromatographic system, including the optimization of the efficiency, sensitivity and instrumentation. Those involved in developing chromatographic methods or wishing to improve existing methods will value the detailed, structured way in which the subject is presented. Because optimization procedures and criteria are described as elements of a complete optimization package, the book will help the reader to understand, evaluate and select current and future commercial systems.

This book was released on 1987-12-01 with total page 471 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is the first of a two-volume project which attempts to treat the sample handling and detection processes in a liquid chromatographic system in an integrated fashion. The need for more selective and sensitive chromatographic methods to help solve the numerous trace analysis problems in complex samples is undisputed. However, few workers realize the strong interdependence of the various steps - sample handling, separation and detection - which must be considered if one wants to arrive at an optimal solution. By introducing a strong element of selectivity and trace enrichment in the sample preparation step, fewer demands are placed on the quality of the chromatography and often a simple UV detector can be used. By using a selective detection mode, i.e. a reaction detector, the sample handling step can frequently be simplified and more easily automated. The impact of such a ``total system'' approach on handling series of highly complex samples such as environmental specimens or biological fluids can be easily imagined. Each chapter includes sufficient references to the literature to serve as a valuable starting point for more detailed investigation. Special emphasis is placed on the sample handling, and high priority has been given to the treatment of chemical principles applied to the topics presented, rather than to instrumentation. Written by experienced practitioners, this volume will be of interest to investigators in many areas of application, including environmental scientists and those active in the clinical, pharmaceutical and bioanalytical fields.

Available in PDF, EPUB and Kindle. Book excerpt: Discover how to use HILIC to analyze and better understand polar compounds An increasingly popular analytical method, hydrophilic interaction chromatography (HILIC) has the ability to retain and separate polar compounds that are often difficult to analyze by reversed-phase high-performance liquid chromatography (HPLC) or other analytical methods. Offering a comprehensive review, this book enables readers to develop a fundamental understanding of how HILIC works and then apply that knowledge to develop and implement a variety of practical applications. Hydrophilic Interaction Chromatography begins with discussions of HILIC retention mechanisms, stationary phases, and general method development. This sets the foundation for the book's extensive coverage of applications. The authors address unique separation challenges for bioanalytical, environmental, pharmaceutical, and biochemical applications. Moreover, there is a thorough discussion of HILIC in two-dimensional chromatography. With contributions from leading analytical scientists who have extensive experience in HILIC as well as HPLC, Hydrophilic Interaction Chromatography serves as a practical guide for researchers, featuring: Detailed examples of HILIC methods and development approaches Thorough explanations of retention mechanisms and the impact of stationary phase and mobile phase properties on separations Step-by-step guidance for developing efficient, sensitive, and robust HILIC methods References to the primary literature at the end of each chapter Hydrophilic Interaction Chromatography is written for scientists who use or develop analytical methods for the separation of polar compounds. In particular, these researchers will discover how HILIC can be used to analyze and better understand the composition of pharmaceutical, bioanalytical, biochemical, chemical, food, and environmental samples.
