Chromatography aims at maximizing the differential migration (separation) of analytes relative to their dispersive transport (peak broadening). This dynamics involves a complex transport scheme with a hierarchy of characteristic time and length scales, from analyte–surface interactions to effective macroscale transport behavior. Here we report on results obtained with a comprehensive modeling approach that combines three-dimensional pore-scale simulations of fluid flow and mass transport, i.e., advection–diffusion in the interstitial void space of a random packing of polydisperse hard spheres (representing a chromatographic bed) with the stochastic model of analyte sorption at the solid–liquid interface of the packing. The retention factor of an analyte is constructed by independent adjustment of the adsorption probability and the mean adsorption time. The approach can realize any microscopic model of the adsorption kinetics based on a distribution of adsorption sojourn times expressed in analytical or nu...
