Contributions from N.A. Izmailov and M.S. Schraiber to the development of thin-layer chromatography (on the 70th anniversary of the publication of the first paper on thin-layer chromatography)

摘要

It is well known that N.A. Izmailov and M.S. Schraiber are the authors of the first paper in thin-layer chromatography (TLC). The detailed analysis of this publication has shown that Izmailov and Schraiber have also proposed the following TLC versions: (i) circular chromatography (this was earlier outlined by F. Geiss), (ii) frontal TLC, (iii) elution TLC, and (iv) frontal elution TLC. The last named version is of interest as a preconcentration method.
