## Abstract Sedimentation FieldβFlow Fractionation (SFFF), which is a oneβphase chromatographic system, is shown to be a rapid and convenient method for the simultaneous determination of particle size and density in polydisperse colloidal samples. This can be done by a methodology based on the vari
The theoretically predicted inverse relationship between the retention Ε½ . parameter for electrical field-flow fractionation FFF and a sample's particle diameter d is verified experimentally using colloids of well-characterized size and electrophoretic mobility. From observed retentions of these sam
