J. Planar Chromatogr. 24, 188-195 (2011). A new method of quasi-continuous videodensitometric recording of circular TLC is proposed. It is based on separation by planar chromatography and simultaneous videodensitometric recording of the chromatograms on the plate as the chromatograms are developing in real time. This new approach enables to expand and to simplify the practical application of separation data of target samples during the entire chromatographic process. The chromatograms are recorded on a plate wetted with the liquid phase in the separation process. Use of this new version of TLC enables considerable reduction of the duration of analysis. Not only the traditional circular TLC is considered, but new methods of circular TLC - corner and lateral circular TLC. Quasi-continuous recording of the separation results can also be used for the detection of compounds in UV light. As example the CAMAG test dye mixture III was separated on silica gel with toluene.
