We propose two thermodynamic relationships which couple analyte retention with selected physicochemical properties - exponential dependence of analyte relative retention times (τ) on boiling points (TB) and molar volume (Vm) or, alternatively, on boiling points and molar refraction (Rm). The statistical performance of these retention models was tested on experimental data obtained for homologous analytes (methyl n-alkyl ketones) by use of isothermal capillary gas chromatography (CGC) on stationary phases of different polarity. Computations were performed by use of Statistica 5.0 PL software. The same models were then used to predict the thermodynamic properties selected (i.e. the molar enthalpies of vaporization of the analytes employed) and their physicochemical performance was evaluated by comparison of the results obtained with those obtained from the literature. The experiments and computations performed led to the conclusion that the models introduced enable prediction of analyte retention and that they can also prove useful for extraction of thermodynamic information from the CGC results.
