(a) Adsorption free energy calculation (RT lnVn or ΔGads) of n-alkanes (nC5–nC12) and alkylbenzenes (toluene up to n-hexylbenzene) according to the Dorris-Gray approach50. The graph depicts the average slope of triplicate injections, allowing for determination of the adsorption dispersive energy of a methylene group (\({\Delta G^{0}_{\rm CH_{2}}}\), see added label in the graph). (b) Retention times of alkanes and alkylbenzenes plotted against their vapour pressures. The lines in the graph represent the average values derived from the triplicate measurements, serving as a visual guide for interpretation. Experiments were performed at 423 K.
