Summary Rapid progress has been made in the last few years in the development of solvation models for gas chromatography. These models are based on the free energy of transfer of a solute from the gas phase to solution consisting of the additive processes of cavity formation and solute-solvent interactions expressed as dispersion, orientation, induction and hydrogen-bond formation. The adaptation of these models to characterize solvent selectivity for a wide range of common stationary phases and to the prediction of retention is critically discussed. The need to use high quality retention data in the further elaboration of solvation models is also demonstrated.
