IN a relatively short time paper chromatography has become an indispensable tool for separating and analysing the most varying kinds of chemical compounds. In the past few years a valuable ...

THE principle of this method is that a relatively voluminous sample (50–100 µl.) is easily applied over a large area of chromatographic substrate and can then be swept into a narrow band by an ...

Thin layer chromatography is used to analyse mixtures: determine the number, identity, and purity of compounds present in a mixture. This technique can also be used to visualize the progress of a ...

High-performance Thin Layer Chromatography (HPTLC) is one of the many sophisticated, flexible, robust, and cost-effective separation techniques employed in the discovery, development, and analysis of ...
