Abstract

Fractions of polystyrene latex sample with very narrow particle size distribution obtained with the aid of micropreparative sedimentation field-flow fractionation (SFFF) were characterized by quasi-elastic light scattering. The measured values of the average particle size of individual fractions confirmed high resolving power of SFFF even for extremely difficult separations of samples with narrow polydispersity.
