heal.abstract	The reversed flow - inverse gas chromatography is a simple and fast technique for the determination of kinetic and energetic parameters, for the degradation diagnosis describing the action of one or two gases simultaneously on a solid surface. The RF-IGC (or RF-GC) method was used to measure directly from experimental data, not only kinetic physicochemical quantities, but also adsorption energies, local monolayer capacities, local adsorption isotherms, the probability density function for the adsorption energies as distributed over the experimental time. This method has been applied by using n-hexane as probe gas and magnesium oxide, chromium oxide, silicon oxide and cadmium sulfide as solid adsorbents. In that way, one can be led to the characterization of heterogeneous surfaces and throw some light to the mechanism of heterogeneous reactions taking place in nature, as the deterioration of monuments and works of art by air pollutants, or in industrial processes.	en
