Abstract
A new method for experimental determination of the thermal diffusion factor α T for binary gas mixtures with a thermal diffusion column (TDC) is developed, based on A. M. Rozen's equation of TDC. The experimental results for α T are obtained in a reduced form in this approximation. An experimental reference point, determined in the same TDC with a standard gas mixture, is used for the transformation of the results for α T in absolute units. The proposed method is applicable for arbitrary gas mixtures, irrespective of the mass difference of the components.
