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.

In 1906, Michael T. Sweet first developed the chromatographic method by using an adsorbant to separate pigments. Since that time, the technological advances in TLC and HPLC have brought about new definitions of purity in parallel with the advances. Radiopharmaceutical chemistry is especially dependent on the chromat ographic technique because of the relatively small amount of material in most radiopharmaceuticals-often so small that the usual physical methods of analytical chemistry cannot be used. As a result, this collection of papers represents the key to successful radiopharmaceutical development by setting the standard for the pres of radiochemical purity. ent-day definition William C. Eckelman, Ph.D. Diagnostics Associate Director The Squibb Institute for Medical Research New Brunswick, New Jersey Preface The chapters herein are updated and expanded versions of presentations that the authors made at a symposium held on June 4, 1984 in Los Angeles, California under the sponsorship of the Radiopharmaceutical Science Council of the Society of Nuclear Medicine. All manuscripts were refereed. The intent of the symposium organizers was to enlist participants who work on a day-to-day basis with the analytical and chromatographic techniques to be discussed at the symposium. We feel confident that this distillation of hands-on experience will be of value to graduate students as well as experienced researchers in radio pharmaceutical chemistry and related fields which use radiotracer methodology.

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.

Chromatographic & Electrophoretic Techniques, Fourth Edition, Volume I: Paper and Thin Layer Chromatography presents the methods of paper and thin layer chromatography. This book discusses the practical approach in the application of paper and thin layer chromatography techniques in the biological sciences. Organized into 18 chapters, this edition begins with an overview of the clinical aspects related to the detection of those metabolic diseases that can result in serious illness presenting in infancy and early childhood. This text then discusses the three major types of screening for inherited metabolic disorders in which paper or thin-layer chromatography are being used, including screening the healthy newborn population, screening the sick hospitalized child, and screening mentally retarded patients. Other chapters consider the procedures for thin layer chromatography. This book discusses as well the complexity of amino acid mixtures present in natural products. The final chapter deals with the detection of synthetic basic drugs. This book is a valuable resource for chemists and toxicologists.
