J. Planar Chromatogr. 35, 207-227 (2022). The paper discussed the applications of the solvation parameter model in TLC, as a transfer model for biphasic systems in which isotropic interactions in each phase are responsible for the preferential solvation of a solute in one phase over the other. The model emphasizes the importance of water in the mobile phase and the general contributions of mobile phase interactions on the retention mechanism. In addition, the selected solvation of the stationary phase in contact with the mobile phase makes an important contribution to system selectivity. System constants for reversed-phase separations on chemically bonded silica gel HPTLC layers with different mobile phases compositions were also discussed and applied to construct correlation diagrams to facilitate the comparison of selectivity for different layers with the same mobile phase composition or different mobile phase compositions for the same layer.
