✦ Synopsis

This review provides a brief overview of particle size characterization by Ž . Sedimentationr Steric Field-Flow Fractionation SdrSt FFF and discusses the retention in steric FFF, the recent findings on hydrodynamic lift forces, and the density compensation calibration procedure for obtaining size distribution of supramicron-sized particles. A number of applications to the determination of particle size distribution are discussed with some practical considerations such as steric inversion diameter, size selectivity, and selection of an optimum calibration run condition.
