abstract

  • The measurement of activity coefficients at infinite dilution by gas chromatography is very attractive but requires validation by static measurements. Previous work concerning polar stationary phases is extended to include polar solutes in nonpolar solvents. Both gas-liquid interface and solid support effects interfere with the determination of activity coefficients. The static behavior of methanol, ethanol, acetone, and diethylamine as solutes in the solvent squalane spread on several solid supports as well as in bulk is described. For meaningful activity coefficients by gas chromatography, the systems should be restricted to small activity coefficients, nonpolar solutes and solvents, and inert solid supports carrying high liquid loads.
