摘要

Thermal field-flow fractionation (thermal FFF) separates efficiently and rapidly polymers and colloidal materials according to their Soret coefficient. A retention model, allowing the thermal conductivity And viscosity of the carrier liquid as well as the Soret Coefficient of the polymer to be dependent of the Temperature has been developed. This model is used To determine the temperature of the Soret coefficient Of polystyrenes in ethylbenzene from experimental Retention data of polymer standards obtained at Various cold wall temperatures. It is found that the Thermodiffusion coefficient increases with increasing Temperatures.
