An adsorption gas chromatography using water vapor as the carrier can be applied to the separation of alcohols and other oxygen-containing organic substances, except polyalcohols and organic acids. The adsorbents made of crushed firebrick powder (SiO2, 50%; Al2O3, 45%; bulk density 0.80) are modified by hydrogen fluoride solution, so that they have 0.40.25 cm of H. E. T. P. and can separate C1C6 alcohols completely without a marked tailing, especially at low temperature. The order of elution for similar type of molecules may depend on the boiling point. It is operated at 110°C to 210°C, and samples are supplied as dilute aqueous solution not exceeding 0.01 %. Water vapor from sample and carrier does not give any unfavorable influence on the separation column and the hydrogen flame ionization detector employed. Neither extinction nor decomposition of the sample is seen during the column separation, an analysis of so dilute aqueous solution as 0.3 ppm can be achieved in this "steam carrier adsorption gas chromatography".
