Gas Chromatographic Method

A rapid gas-chromatographic method is described for the quantitative analysis of the equilibrium vapor phase over a solution. A vapor pump has been designed for the purpose and is described. The method should be particularly useful at low concentrations of volatile solutes, alone or in mixtures. As an example of the application of the method, the vapor concentrations of methanol and of ethanol over benzene solutions at 25 °C have been measured. The precision of the data is also reported. The activity coefficients of the alcohols in the benzene solutions were calculated.
