Axial dispersion coefficients and Peclet numbers for fixed beds of various fine particles were measured within the range of mean particle diameter from 4.8×10-5m to 1.7× 10-4m, and that of Reynolds number from 1.0× 10-2 to 2.0. From the experimental results, the effects of Reynolds number, particle diameter and particle size distribution on the Peclet number were investigated and a correlation was proposed. It was suggested from the results of simulation of the chromatogram for preparative HPLC that the Peclet number affected the shape of the chromatogram when the linear velocity of mobile phase was low and the adsorption coefficient was small.
