The gas-liquid chromatographic (GLC) method of measuring the activity coefficient of the solute in a binary system has been extended from infinite dilution to the finite concentration range. An equation is presented relating the retention volume of the injected solute sample to the equilibrium solute concentration present in the column. This relation permits determination of the activity coefficient of the solute. Based on the experimental results obtained from the study of the two binary systems, benzene in diethylene glycol at 50°, 70°, and 90°C. and n-hexane in 1,2,4-trichlorobenzene at 30°C., the activity coefficients of the solute measured by the GLC method were found to agree within about ±5% with those obtained by the static equilibrium method.
