This book was released on 1972 with total page 3 pages. Available in PDF, EPUB and Kindle. Book excerpt: The quaternary nitrogen drugs present some problems when identifying them in a mixture of drugs or in tissues. This note describes a TLC (thin-layer chromatography) method by which microgram amounts of quaternary nitrogen drugs can be separated and tentatively identified in less than 30 min.

Download or read book Quantitative Thin Layer Chromatography written by Bernd Spangenberg and published by Springer Science & Business Media. This book was released on 2011-01-03 with total page 399 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Thin Layer Chromatography in Drug Analysis written by Lukasz Komsta and published by CRC Press. This book was released on 2013-12-20 with total page 1070 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: Plant Drug Analysis has proven an invaluable and unique aid for all those involved with drug production and analysis, including pharmacists, chemical and pharmaceutical researchers and technicians, drug importers and exporters, governmental chemical control agencies, and health authorities. From the reviews of the German Edition: "The reviewer would like to recommend this excellent book to all chromatographers, as he considers it highly relevant to the solution of numerous problems. Its main purpose is the demonstration of thin-layer chromatograms of the usual commercial drugs as an aid in testing for identity and purity. ... 165 colour plates, each showing 6 chromatograms and all of superb quality photographs ..."
