Established ion chromatography techniques have changed little since the 1980s but a new technique, high performance chelation ion chromatography (HPCIC), has revolutionized the area. HPCIC enables a much greater range of complex samples to be analyzed and this is the first comprehensive description of its use in the trace determination of metals. Written by world leaders in the field, it is aimed at professionals, postgraduates, chromatographers, analytical chemists, and industrial chemists. The book describes the underlying principles which give rise to the special selectivities that can be chosen for separating specific groups of metals. It also covers the latest research and gives many examples of its application to real samples. The very latest developments in detection techniques are included showing that HPCIC can rival atomic spectroscopic techniques such as ICP-MS. The detailed description of the fundamental principles controlling the separation of trace metals using chelating substrates is unique to this book. It shows how HPCIC differs from the commonly used simple ion exchange techniques and how these chelation characteristics give rise to a much more useful and versatile metal separation system. Readers will also be interested in the analysis of extremely difficult matrices, such as saturated brines, easily achieved by HPCIC but requiring very complex multi column systems using other ion chromatography methods.

Gradient elution demystified
Of the various ways in which chromatography is applied today, few have been as misunderstood as the technique of gradient elution, which presents many challenges compared to isocratic separation. When properly explained, however, gradient elution can be less difficult to understand and much easier to use than often assumed.
Written by two well-known authorities in liquid chromatography, High-Performance Gradient Elution: The Practical Application of the Linear-Solvent-Strength Model takes the mystery out of the practice of gradient elution and helps remove barriers to the practical application of this important separation technique. The book presents a systematic approach to the current understanding of gradient elution, describing theory, methodology, and applications across many of the fields that use liquid chromatography as a primary analytical tool.
This up-to-date, practical, and comprehensive treatment of gradient elution:
* Provides specific, step-by-step recommendations for developing a gradient separation for any sample
* Describes the best approach for troubleshooting problems with gradient methods
* Guides the reader on the equipment used for gradient elution
* Lists which conditions should be varied first during method development, and explains how to interpret scouting gradients
* Explains how to avoid problems in transferring gradient methods
With a focus on the use of linear solvent strength (LSS) theory for predicting gradient LC behavior and separations by reversed-phase HPLC, High-Performance Gradient Elution gives every chromatographer access to this useful tool.

The Hydrogen Bond and the Water Molecule offers a synthesis of what is known and currently being researched on the topic of hydrogen bonds and water molecules. The most simple water molecular, H2O, is a fascinating but poorly understood molecule. Its unique ability to attract an exceptionally large number of hydrogen bonds induces the formation of a dense "hydrogen bond network" that has the potential to modify the properties of the surrounding molecules and their reactivities. The crucial role that water molecules play is described in this book. The author begins by providing an overview of the thermodynamical and structural properties of H-bonds before examining their much less known dynamical properties, which makes them appear as centres of reactivity. Methods used to observe these components are also reviewed. In the second part of the book the role played by the dense H-bond network developed by H2O molecules is examined. First in ice, where it has important atmospheric consequences, then in liquid water, and finally in macromolecules where it sheds some original light on the fundamental question "How is it that without water and hydrogen bonds life would not exist?."
This book will be of interest to researchers in the fields of physics, chemistry, biochemistry and molecular biology. It can also serve as a teaching aid for students attending course in chemical physics, chemistry or molecular biology. Engineers involved the water industry would benefit from reading this book, as would scientists working in pharmaceutics, cosmetics and materials.

This book examines Thomas Hardy's representations of the road and the ways the archaeological and historical record of roads inform his work. Through an analysis of the uneven and often competing road signs found within three of his major novels - The Return of the Native, Tess of the D'Urbervilles, and Jude the Obscure - and by mapping the road travels of his protagonists, this book argues that the road as represented by Hardy provides a palimpsest that critiques the Victorian construction of social and sexual identities. Balancing modern exigencies with mythic possibilities, Hardy's fictive roads exist as contested spaces that channel desire for middle-class assimilation even as they provide the means both to reinforce and to resist conformity to hegemonic authority.

The development of chiral liquid chromatography, facilitating the straightforward separation of enantiomers, was a significant advance in chromatography, leading to widespread application in analytical chemistry. Application in preparative chromatography has been less rapid, but with the development of single enantiomer pharmaceuticals its use is increasingly common in chemical synthesis at laboratory, pilot plant and even full production scale.

Written for chemists, chemical engineers and analytical chemists, Preparative Enantioselective Chromatography demonstrates the considerable utility of the technique in contemporary discovery, development and production scale chemistry. By briefly covering basic preparative chromatography then developing the discussion to cover chiral stationary phases for preparative use, method development and practical applications, the first part of this book serves as an ideal introduction to the technology for laboratory and pilot plant scale application. The more detailed information presented in the later chapters, on applications in discovery, process development and large scale or production environments, including case studies and equipment selection issues, ensures the book will serve as a sound reference for experienced separation scientists.
