Thin-layer chromatography (TLC) is widely used particularly for pharmaceutical and food analysis. While there are a number of books on the qualitative identification of chemical substances by TLC, the unique focus here is on quantitative analysis. The authors describe all steps of the analytical procedure, beginning with the basics and equipment for quantitative TLC followed by sample pretreatment and sample application, development and staining, scanning, and finally statistical and chemometric data evaluation and validation. An important feature is the coverage of effect-directed biological detection methods. Chapters are organized in a modular fashion facilitating the easy location of information about individual procedural steps.

This book is the first example in presenting LC-MS strategies for the analysis of peptides and proteins with detailed information and hints about the needs and problems described from experts on-the-job. The best advantage is -for sure- the practical insight of experienced analysts into their novel protein analysis techniques. Readers starting in 'Proteomics' should be able to repeat each experiment with own equipment and own protein samples, like clean-up, direct protein analysis, after (online) digest, with modifications and others. Furthermore, the reader will learn more about strategies in protein analysis, like quantitative analysis, industrial standards, functional analysis and more.

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.

Analytical techniques based on separation processes, such as chromatography and electrophoresis, are finding a growing range of applications in chemical, pharmaceutical and clinical laboratories. The Wiley Separation Science Series provides the analyst in these laboratories with well-focused books covering individual techniques, so that they can be applied more efficiently and effectively to contemporary analytical problems. The different enantiomers of a drug can exhibit widely different physiological activity in degree and nature. As a result, the separation and identification of enantiomers is now a very important analytical problem and chiral chromatography is the natural technique to apply to the resolution of such mixtures. Chiral Chromatography provides the reader with a basic understanding of the nature of chromatographic separations and relates the principles specifically to the separation of enantiomers. The following information is included:

• chiral separations involving both gas and liquid chromatography
• descriptions of the apparatus used for both techniques
• detailed discussion on the retention mechanism that results in chiral selectivity
• the structure and synthesis of a wide range of chirally active stationary phases used in both gas and liquid chromatography
• preparative applications for large scale purification of enantiomers
• applications of capillary electrophoresis and capillary electrochromatography.

The porphyrins, chlorophylls, bilins and related tetrapyrroles are vital for all living organisms. Natural and synthetic tetrapyrroles are used extensively in foods, cosmetics, biotechnology, pharmaceuticals, diagnostics and medicine. Methods for their separation and characterization therefore, have a very wide area of applications. Yet, there is a dearth of books dedicated to HPLC and HPLC/MS of tetrapyrroles. Lim addresses this problem admirably by providing practical HPLC and HPLC/MS protocols coupled with in-depth chromatographic and mass spectrometric reference data. These are invaluable in the analysis, identification and characterization of porphyrins, chlorophylls, bilins and other related compounds found in biological and clinical materials. HPLC method development and optimization for coupling to mass spectrometry are also described in rich detail. Sample preparation, and suggestions for avoiding procedural artifacts during extraction of clinical and biological samples are discussed. Clinical biochemists involved in biochemical diagnosis of human porphyrias will find this monograph assuredly helpful, as would analysts, biochemists and chemists involved in the separation, isolation and characterization of natural and synthetic tetrapyrroles. Undoubtedly, Lim has contributed a master-piece containing sufficient background material for beginners and up-to-date references for all researchers in the field.
