The steam carrier adsorption gas chromatography may be applicable to the analysis of polyalcohols, fatty acids, phenols and amines.<BR>A crushed insulating firebrick (SiO<SUB>2</SUB> 50%; Al<SUB>2</SUB>O<SUB>3</SUB> 45%; and others), modified by potassium fluoride for diols, or added further a little phosphoric acid for glycerol, being packed in a glass column, serves as adsorbents, through which steam may carry these materials separately without remarkable tailing at comparatively low temperature (130°C), even an aqueous sample being separable.<BR>The separation columns for fatty acids up to C<SUB>18</SUB>, phenol, cresol and alkyl-phenols by steam carrier without any troubles are prepared by heating at 500 °C a glass column containing firebrick powder to which 13% phosphoric acid is absorbed. These columns can be detectable at the concentration lower than 1 ppm aqueous solution of low fatty acids and phenols, by a hydrogen flame ionization detector. To use these acidic columns, alkaline metal salts of fatty acids show the similar figure of chromatogram to the free acids.<BR>Amines can be eluted fractionally through the separation column of magnesia powder and an aluminum pipe with so little tailing that analysis of dilute aqueous samples of alkyl-amines, pyridine, aniline and their derivatives (including hydrogen chloride salts) is achieved.<BR>These chromatographys are operated at 100°C to 230 °C.<BR>This method might be expected to be applicable to more organic chemicals.
