Particle size analysis of dilute environmental colloids by flow field-flow fractionation using an opposed flow sample concentration technique.

Abstract

An on-line concentration method has been developed for the analysis of dilute suspensions of macromolecules and particles by flow field-flow fractionation (FFF). This method, termed opposed flow sample concentration (OFSC), uses two opposing flowstreams to focus sample into a narrow band near the inlet of the flow FFF channel. Large sample volumes (up to 1… (More)
