Variants of Thin-layer Chromatography with Controlled Flow of the Mobile Phase

The review is devoted to the methods for controlling the flow of the mobile phase which have been developing successfully in thin-layer chromatography (TLC). Their use makes it possible to eliminate some of the principal disadvantages of the traditional TLC with retention of the majority of its advantages. The continuous variant, the continuous variant with flow type detection, the centrifugal variant of TLC, and also the variant of TLC under pressure are examined. It is shown that control of the flow of the mobile phase makes it possible not only to employ TLC successfully for the selection of separation conditions in column liquid chromatography (CLC) but also to approach CLC as regards performance and speed. At the same time it gives rise to new possibilities for the automation of TLC.
