| Abstract: | A method for measuring diffusing coefficient with reversed-flow gas chromatography is reported. The reversed-flow gas chromatographic formula for measuring diffusion coefficient by katsanos is modified to make it applicable to liquid samples. The diffusion coefficients of pentane, hexane, heptane, acetone, ethyl alcohol, isopropyl alcohol and cyclohexane are measured with the modified formula. |

| Keywords: | Gas chromatography diffusion coefficient reversed flow gas chromatography |
