Steam can be used as the carrier gas for gas-solid adsorption chromatography so that mixtures of alcohols and organic acids are separated without any marked tailing. A crushed diatomaceous fire brick containing a little phosphoric acid and activated alumina serve as good adsorbents for alcohols, ketones and esters and for hydrocarbon mixtures, respectively. Use of the steam as the carrier gas may considerably extend the applicability of adsorption gas chromatography. Water-containing samples can also be subject to the analysis without any difficulty. Even the separation of 0.5ppm C<SUB>1</SUB>C<SUB>4</SUB> alcohols in aqueous solution can be achieved in this way.
