Abstract

Field-flow fractionation (FFF) is a family of high-resolution-techniques for separating and characterizing polymeric, colloidal and particulate material. Applications have spanned a tremendous mass range, from molecules as small as 1000 molecular weight to particles 100 μm in diameter. FFF is primarily used to obtain the molecular weight or size distribution of these materials. However, FFF is also an excellent tool for pre-fractionating heterogeneous samples into more homogeneous subfractions, to be further analyzed by techniques that could not otherwise have been successfully implemented due to the complexity of the original sample. In the work presented here, we focus on the application of FFF to industrial materials, including polymer gels, ceramics, carbon black, quartz, clay, silica, alumina, and titania.
