This is derived by comparing a recent theory of SEC with the theory of Giddings and Eyring for the adsorption chromatography. The elution volume is the excluded volume divided by the mean fraction of the analyte in mobile phase. Relations between the probabilities of adsorption and desorption of the molecule and the fractions of the analyte in MP and SP were derived.
