- Аннотация: The micro-thermal field-flow fractionation (micro-TFFF) technique was proposed and continuously developed for analytical separations of macromolecular and particulate species of synthetic, natural, and biological origins. Progress in the theory of the separation mechanisms of micro-TFFF inspired improvements in experimental methodology and instrumentation. On the other hand, important advancements in constructing more powerful apparatuses permitted performance in analytical separations close to the predicted theoretical limits. The surface properties of colloidal particles exposed to a temperature gradient fundamentally influence their migration. Spherical particles of identical size but differing surface properties migrate differently in a temperature gradient. The shape and surface topographical heterogeneity of the particles also distinguish their thermal diffusion. It was anticipated and theoretically calculated that separations of colloidal particles based on these particular differences could be achieved using micro-TFFF. Theoretical conclusions were confirmed by real separations of various particulate species, including living bacterial cells.
