Thin-Layer Chromatography
Author: Peter E Wall
Publisher: Royal Society of Chemistry
ISBN: 1847552463
Category : Science
Languages : en
Pages : 195
Book Description
Thin-Layer Chromatography (TLC) is a modern, reliable tool that complements other chromatographic techniques. This book provides a practical guide to the basic principles, procedures and pitfalls on the practical application of TLC. Thin Layer Chromatography: A Modern Practical Approach offers a sequence of chapters following the steps of the technique as the chromatographer would follow them. The chapters provide a choice of sorbent best suited to the separation intended, followed by pre-treatment required for the sample, applying the sample to the sorbent layer, development procedure, visualisation and detection, and finally quantification. Imaging and hyphenation techniques are described. The reasons why recommendations are made for specific and more general methods are covered. The book also provides an overview of some recent developments in the field.

Thin Layer Chromatography in Drug Analysis
Author: Lukasz Komsta
Publisher: CRC Press
ISBN: 1466507152
Category : Medical
Languages : en
Pages : 1070
Book Description
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.

Quantitative Thin-Layer Chromatography
Author: Bernd Spangenberg
Publisher: Springer Science & Business Media
ISBN: 364210729X
Category : Science
Languages : en
Pages : 399
Book Description
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.

Modern Phytochemical Methods
Author: Nikolaus H. Fischer
Publisher: Springer Science & Business Media
ISBN: 1468490605
Category : Science
Languages : en
Pages : 412
Book Description
This volume contains reviews which are based on a symposium, given th at the 30 meeting of The Phytochemical Society of North America, held at Laval University in Quebec City, Canada on August 11-15, 1990. During the past two decades, there have been major new developments in methods which can be applied toward the isolation, separation and structure determination of complex natural products. Therefore, the topic of this symposium, "Modem Phytochemical Methods", is a very timely one. The organizers of the symposium recognized that it would not be possible to cover in detail all new advances in phytochemical methodology. It was therefore decided to emphasize general reviews on recent developments of major separation techniques such as high performance liquid chromatography as well as supercritical fluid chromato graphy. In addition, advances in commonly used structure determination methods, mainly NMR and MS, are reviewed. Other topics include methodo logies of micro-sampling for isolation and analysis of trichome constituents as well as recent breakthroughs on biosynthetic studies of monoterpenes using "enriched" basal cells of trichomes. The volume concludes with a review of quantitative structure-activity relationship (QSAR) studies of biologically active natural products. In Chapter I, K. Hostettmann and his colleagues give a general review of recent developments in the separation of natural products with major emphasis on preparative separations of biologically active plant constituents. The authors present a comparison of droplet countercurrent chromatography (OCCC) with the highly rapid and more versatile centrifugal partition chromatography (CPC).
