Based on the stoichiometric displacement model of retention in liquidd chromatog. the solvent strength eab of a binary solvents mixture may be considered as a function of the active component concentration [DB] in mobile phase and the relation is expressed as: eab = eab0 + S log [DB], where eab0 is the standard solvent strength parameter, S is the factor relating to its selectivity; [DB] is the mole concentration of the active component in th solution Data from literatures were used to test the reliability of the relationship. The phys. meanings of eab, eab0, and S are discussed.2
