The methodology of generalized dispersion theory is used to predict the breakthrough curves. The functions, f 0 and f 1, are determined by introducing a two-dimensional Sturm—Liouville operator. The results suggest that the side wall effects on the axial dispersion cannot be neglected and a dispersion equation with time dependent coefficients is appropriately describable of the practical field-flow fractionation system.
