Correlation between surface diffusion and molecular diffusion in reversed-phase liquid chromatography
Article Abstract:
Surface diffusion data measured for different compounds, mobile phase solvents, stationery phases, and temperatures in reversed-phase liquid chromatography are reevaluated to study the mechanism of surface diffusion. The results show a correlation between surface diffusion coefficients and molecular diffusivity.

Thermodynamic characteristics of surface diffusion in reserved-phase liquid chromatography
Article Abstract:
Results indicate that reversed-phase liquid chromatographic (RPLC) surface diffusion activation energy analysis points to a restricted diffusion model for the mass transfer mechanisms implicated in surface diffusion. Data also suggest that this model is consistent with the RPLC surface diffusion characteristics.

Comparison of the characteristics of adsorption equilibrium and surface diffusion in liquid-solid and gas-solid adsorption on C18-silica gels
Article Abstract:
A study of four parameters characterizing the adsorption equilibrium, surface diffusion, and related thermodynamic properties derived from pulse-response experiments in various reversed-phase liquid chromatography (RPLC) systems with the use of C18-silica gels and aqueous solutions are reported.
