This book provides an up-to-date insight into the chemistry behind the colour of the dyes and pigments that make our world so colourful. The impressive breadth of coverage starts with a dip into the history of colour science. Colour Chemistry then goes on to look at the structure and synthesis of the various dyes and pigments, along with their applications in the traditional areas of textiles, coatings and plastics, and also the ever-expanding range of "high-tech" applications. Also discussed are some of the environmental issues associated with the manufacture and use of colour. The broad and balanced coverage presented in this book makes it ideal for students and graduates. In addition, many specialists in industry or academia will also benefit from the overview of the subject that is provided.

Many new methods directed to organic and inorganic syntheses of useful intermediates are being developed to specifically address green and sustainable chemistry principles. Highlighting the importance of green metrics, the Green Syntheses series focuses on how to reliably substantiate and validate the level of "greenness" of chemical processes, providing practical synthetic methodologies and metrics for a rigorous proof of "greenness." In Green Syntheses, Volume 1, the first book of its kind, the editors determine appropriate material efficiency green metrics and use them to compare syntheses provided by the chapter authors with those previously published. Presenting a new concept in green chemistry, this book demonstrates what future publications might look like if green principles are followed and also incorporate the important ethical aspect of supplying rigorous procedures in laboratory practice and evidence of greenness of a given synthesis protocol using metrics analysis. This inaugural volume initiates the much-needed transition from stating the 12 guiding principles on the philosophy of green chemistry to the actualization and verification of it. The book addresses primarily the issue of material efficiency metrics, which measure the amount of waste produced relative to desired product. In each contributed example, full experimental details are given showing all quantities of materials used in the procedure. Authors discuss the green merits of their protocols in conjunction with the results of a thorough metrics analysis, allowing for in-depth discussion of insights about synthesis strategy and performance characteristics of the new and prior cited plans.

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 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.
