Book Description :

Forced-Flow Layer Chromatography takes a close look at the specifics of forced-flow layer chromatography techniques, from their evolution to the nuances of using these techniques in a variety of applications where traditional thin-layer chromatography (TLC) and high-performance thin-layer chromatography (HPTLC) are not as effective. This book presents a number of variations of TLC techniques, with special emphasis on the overpressured-layer chromatography (OPLC) technique and newer developments such as the BioArena System for biomedical analysis. The versatility of these forced-flow techniques opens up new avenues for the analysis of a large number of samples for high-throughput screening and for the analysis of very complex matrices, while the development of BioArena extends the use of these techniques to challenging new areas of bioanalysis. Details a variety of forced-flow techniques, explaining how they markedly reduce developing time and result in less lateral diffusion and more compact spots Emphasizes the benefits of OPLC separation techniques, a method pioneered by the authors nearly forty years ago Discusses new developments, such as the BioArena system used to facilitate detection, isolation, and identification of new antimicrobials, antineoplastics, biopesticides, and other biologically active substances

Book Description :

For many years TLC has suffered from the image of being a low sensitivity, low resolution, non-quantitative teehnique, suitable for chemists, but not a tool for real ehromatographers. Whilst perhaps true in the past this attitude no longer ref1eets the eapabi1ities of modern instrumenta1ized TLC in all its many forms. This volume represents the proceedings of a meeting in Brighton in 1987 whieh formed part of a eontinuing series of one and two day events on TLC organized by the Chromatographie Soeiety either alone or, like this one, in eonjunetion with other learned bodies. These meetings are designed to keep ehromatographers up to date with the latest deve10pments and help promote a more positive image of TLC. lan Wilson November 1987 v CONTENTS The Chromatographic Society xi Contemporary Thin-layer Chromatography: An introduction IoD.

Book Description :

In the study and conservation of art and artifacts, natural organic materials are frequently encountered in components such as coatings, binders, and adhesives. The identification of these materials is often crucial to the attempt to characterize the technologies employed by artists or craftspeople, understand the processes and causes of deterioration, and plan appropriate conservation treatments. Yet the limited resources of many conservation laboratories put many analysis techniques beyond their reach. Thin-layer chromatography can help fill this gap. The volume consists of a handbook, protocols, and guide to reference materials. The handbook serves as a primer for the basic application of thin-layer chromatography to the analysis of binding media, adhesives, and coatings found on cultural objects; the protocols provide step-by-step instructions for the laboratory procedures involved in typical analyses; and the guide to reference materials aids in the understanding of the types of materials and documentation needed for accurate analyses by thin-layer chromatography.
