Sedimentation field-flow fractionation (sedimentation FFF) is a new technique that has been used to separate and characterize a variety of submicron particles. With the aid of a newly developed on-channel concentration procedure, sedimentation FFF was used to study the colloidal particles contained in samples collected from the Colorado, Green, and Price Rivers in eastern Utah during the spring run-off season. Samples from the different rivers displayed distinctly different fractograms, which could serve to “fingerprint” and characterize the colloidal content. The fractions obtained, when analyzed, displayed distinct differences in chemical composition. Each fraction re-emerged at its original elution volume when re-injected into the apparatus, indicating that the sedimentation FFF procedure had successfully concentrated then fractionated the colloidal particles in the river water. |
