✦ Synopsis


A statistical analysis has been made of the results obtained for the movement of simple dye-mixtures on coated glass plates and commercially available .,factorycoated tubes and foils. The results show that the serious shortcoming,'of -variability .of the .adsorbent, layer on glass which rendered consistent, standardised ,results impractical may be partially overcome with the precoated.tubes and.foils..,

The object of this paper was to investigate esperimentally the reproducibility of RF values in thin-layer chromatography, and to establish the effect of the adsorbent, the molecular structure of the solute and. the solvent on this reproducibility. In order to solve the problem in question, silica g
