A new method of quasi-continuous videodensitometric recording of circular thin-layer chromatography (TLC) is proposed. It is based on separation by planar chromatography and simultaneous quasicontinuous videodensitometric recording of the chromatograms on the plate as the chromatograms are developing in real time. This new approach to recording of separation results enables one to expand and simplify substantially the practical application of data on the separation of samples being studied during the entire chromatographic process. It is important to note that the chromatograms are recorded on a plate wetted with the liquid phase (i.e., on a ‘wet’ TLC plate) in the separation process. Use of this new version of TLC enables considerable reduction of the duration of analysis. It should be noted that in this paper we consider not only the traditional circular TLC, but new methods of circular TLC — corner and lateral TLC. Quasi-continuous recording of the separation results can also be used for the detection of compounds in UV light.
