This study presents a new method for characterizing the polar physicochemical properties of solid surfaces using inverse gas chromatography (IGC) at infinite dilution. The method incorporates the temperature-dependent cross-sectional surface area and London dispersive surface energy of molecules, which significantly affect the surface thermodynamic parameters of solid materials. The thermal Hamieh model and London dispersed surface energy are proposed to better characterize the physicochemical properties of solid surfaces. The new methods provide higher accuracy compared to conventional methods such as the Schultz method. The study addresses controversies and challenges in determining the surface physicochemical properties of solid particles, contributing to a more comprehensive understanding of the surface thermodynamic behavior of solid surfaces. The results show that the London dispersive surface energy of solid surfaces decreases with increasing temperature. The study also determines the specific enthalpy and entropy of polar molecules adsorbed on solid materials, as well as the Lewis acid–base properties of the materials. The results demonstrate that the polycrystalline surface exhibits higher basic constants than the single-crystalline surface. The study highlights the importance of considering temperature effects on surface properties and provides a more accurate characterization of solid surfaces. The results are compared with those obtained using other methods, showing significant differences, particularly in the values of the London dispersive surface energy. The study concludes that the thermal model provides more accurate results for the surface properties of solid materials.This study presents a new method for characterizing the polar physicochemical properties of solid surfaces using inverse gas chromatography (IGC) at infinite dilution.
