Continuous-flow ultracentrifugation (CFUC) was used to separate soil microparticles (SMP) on the basis of theoretical particle size (Stokes' law), and the results were compared with those from swing rotor centrifugation. Clay and soil particles were clearly separated on the basis of theoretical particle size, which was confirmed by a laser-scattering particle-size distribution analysis. These results indicate that CFUC is useful for size fractionation of SMP.
