Used routinely in drug control laboratories, forensic laboratories, and as a research tool, thin layer chromatography (TLC) plays an important role in pharmaceutical drug analyses. It requires less complicated or expensive equipment than other techniques, and has the ability to be performed under field conditions. Filling the need for an up-to-date, complete reference, Thin Layer Chromatography in Drug Analysis covers the most important methods in pharmaceutical applications of TLC, namely, analysis of bulk drug material and pharmaceutical formulations, degradation studies, analysis of biological samples, optimization of the separation of drug classes, and lipophilicity estimation. The book is divided into two parts. Part I is devoted to general topics related to TLC in the context of drug analysis, including the chemical basis of TLC, sample pleparation, the optimization of layers and mobile phases, detection and quantification, analysis of ionic compounds, and separation and analysis of chiral substances. The text addresses the newest advances in TLC instrumentation, two-dimensional TLC, quantification by slit scanning densitometry and image analysis, statistical processing of data, and various detection and identification methods. It also describes the use of TLC for solving a key issue in the drug market-the presence of substandard and counterfeit pharmaceutical products. Part II provides an in-depth overview of a wide range of TLC applications for separation and analysis of particular drug groups. Each chapter contains an introduction about the structures and medicinal actions of the described substances and a literature review of their TLC analysis. A useful resource for chromatographers, pharmacists, analytical chemists, students, and R&D, clinical, and forensic laboratories, this book can be utilized as a manual, reference, and teaching source.

This book is a distillation of twenty years of practical experience of the high pressure liquid chromatography (HPLC) process. Deliberately steering clear of complex theoretical aspects, this book concentrates on the everyday problems associated with the technique, making it perfect for frequent use in the laboratory and for those in the pharmaceutical, agrochemical and biotechnology industries for the analysis and purification of drugs, small molecules, proteins and DNA.

For more than four decades, scientists and researchers have relied on the Advances in Chromatography series for the most up-to-date information on a wide range of developments in chromatographic methods and applications. Volume 44 of this authoritative series once again compiles the work of expert contributors in order to present timely and cutting-edge reviews on a variety of related topics.
Each author's clear presentation of topics and vivid illustrations make the material in Advances in Chromatography: Volume 44 accessible and engaging to biochemists and analytical, organic, polymer, and pharmaceutical chemists at all levels of technical skill.

Focusing on what has been one of the driving forces behind the development of lab-on-a-chip devices, Separation Methods in Microanalytical Systems explores the implementation, realization, and operation of separation techniques and related complex workflows on microfabricated devices. The book details the design, manufacture, and integration of diverse components needed to perform an entire analytical procedure on a single miniaturized device. The content applies to a diversity of disciplines including chemical analysis, biomedical diagnostics, environmental monitoring, and drug discovery.

Separation Methods in Microanalytical Systems lays its theoretical background in a way that scientists from varied disciplines can approach. The book describes factors that influence the performance of separation, such as microfluidic handling, sample pre-treatment, and detection. It also conveys fabrication and material issues, design challenges, and practical considerations. Several chapters describe specific separation techniques that are central to micro-Total Analysis Systems (-TAS) as well as novel methods and emerging trends in microchip-based separations. The book also provides an applications overview that supplies a wealth of examples that help scientists put their ideas in perspective with already existing solutions.

This multi-authored volume offers different styles, approaches, and opinions for a given problem, reflecting the various angles researchers take to handle the same issues. A one-stop guide for understanding, designing, and working with separation techniques in microanalytical devices, Separation Methods in Microanalytical Systems is a valuable reference for scientists andengineers already preparing to meet the anticipated demand for function-specific chemical separation systems.

Chromatography has been developed as a powerful and rapid technique for the separation of compounds with highly similar molecular characteristics, even from complicated matrices. Due to their excellent separation characteristics and versatility, chromatographic methods have found growing acceptance and application in environmental protection for residue analysis in air, ground and surface waters, sewage, sludge, and soil matrices. This is a compilation and concise evaluation of results in this rapidly developing domain of chromatography, with a brief enumeration of the methods applied and a critical discussion of the results. The book gives gas-liquid, thin-layer, high-performance liquid, supercritical fluid chromatographic and capillary electrophoretic analysis of pollutants belonging to different compound classes. The book should be of interest to analytical chemists in legalisation and research, and analytical control specialists, as well as researchers and students.

This work introduces scientists of all disciplines to the chromatographic process and how it functions. The basic principles of chromatographic separation and specific chromatographic procedures, including gas, liquid and thin-layer chromatography, are covered. For each separation method the book details its characteristics, the instrumentation required, the procedures necessary for effective use, areas of application and examples of its use.;This work is intended for analytical chemists, laboratory technicians, and upper-level undergraduate and graduate students in analytical chemistry or separation science courses.

"Handbook of Chromatography: Analysis of Lipids" provides a valuable review of state-of-the-art applications of chromatographic techniques (TLC, GC, HPLC) and other analytical techniques. Much of this volume is devoted to applications of HPLC (including supercritical fluid chromatography) in the analysis of lipids such as fatty acids, oxygenated fatty acids, enantiomeric acyl- and alkylglycerols, and lipoproteins. The handbook also provides extensive coverage of applications of combinations of various chromatographic techniques used in the analysis of ozonides, anacardic acids, glycerophospholipids, products of lipolysis, artifacts and contaminants in edible fats, acylated proteins, non-caloric lipids, lipophilic vitamins, acyl-Coenzyme A thioesters, dolichols, mycolic acids, technical fats and fat products, and liposomes.
"Handbook of Chromatography: Analysis of Lipids" will be a useful reference for oil chemists, biochemists, fat science technologists, and other scientists involved in lipid research.

A source of information on chromatographic techniques and methodologies for the solution of analytical and preparative problems applicable across many disciplines. Entries are arranged alphabetically from Absorbance Detection in Capillary Electrophoresis to Zone Dispersion.
