Abstract
The relationship between the thermodynamic quality of mobile phases and their strength ε was studied for the critical conditions of liquid chromatography. The chromatography of reference polystyrene samples was carried out in the adsorption and exclusion modes, and also under critical conditions, with binary mobile phases and a silica gel column used. The thermodynamic quality of solvent mixtures with respect to one another was evaluated by the intrinsic viscosity [η].
