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.
