Strategy of preparative separation of organic compounds by thin-layer chromatographic methods

摘要

The preparative layer chromatography discussed in this review has been presented to facilitate the choice of the most effective, selective, cheap, and simplest method for separation and isolation of small quantities of some mixture components. Therefore, apart from very effective forced-flow development methods, the possibilities and applications of very simple sandwich chambers ES and DS are discussed. Both forced-flow and continuous planar chromatography development may be considered as quasi column preparative chromatography, carried out on smaller scale. Numerous application examples are also cited in this paper.
