Calvin Giddings Field-Flow Fractionation Research Center, Department of Chemistry, University of Utah, Salt Lake City, UT 84112 Thermal field-flow fractionation, an FFF method in which the driving force is generated by a temperature gradient, has proven highly effective in the separation and analysis of lipophilic synthetic polymers. Thermal FFF is more flexible than SEC (GPC) and, because the FFF channel has no packing, there is less risk of shear degradation, clogging, and system degradation.

Ch003 Conclusions The capability of SdFFF to achieve the separation and characterization both of narrow and broad distributions of polymeric latex beads, along with aggregated latex populations, and to fractionate particles either denser or less dense than the carrier liquid, is demonstrated here. Examples are provided using both latex standards and industrial latexes. Equations are given to help select experimental conditions needed to achieve desired resolution levels. It is also shown that particle size distributions, even for complex multimodal particle distributions, can be derived from the SdFFF elution profiles.
