Abstract Infinite dilution activity coefficients (γ ∞ ) in binary liquid mixtures are data of wide practical and theoretical applicability, but their extensive use has been hindered by the experimental limitations of classical vapor‐liquid equilibrium techniques. Two new experimental methods for accurate γ ∞ determinations are presented. These techniques, both faster and more accurate than classical methods, are complementary, and their applicability to different types of binary systems is discussed.
