Transport characteristics were determined in the gas/solid as well in the liquid/solid systems by combination of Graham’s diffusion cell and inverse liquid chromatography (ILC) technique. Based on the counter-current gas diffusion measurements carried out in Graham’s diffusion cell with inert gases (H2, He, N2 and Ar) the optimum transport parameters were found. Effective diffusion coefficients for two polystyrene samples with different relative molecular weight 1000 and 100,000 in cyclohexane were determined from the responses of a chromatographic column packed with the bone-like hydroxyapatite were found to be 5.92x10-17 and 6.54x10-17 cm2/s, respectively.
