A method has been recently proposed for determining the value of the surface tension of a solid in the absence of adsorption, gammaS0, using material properties determined from vapor adsorption experiments. If valid, the value obtained for gammaS0 must be independent of the vapor used. We apply the proposed method to determine the value of gammaS0 for four solids using at least two vapors for each solid and find results that support the proposed method for determining gammaS0.
