| Abstract | MIXTURES OF HYDROCARBONS, ALCOHOLS, ORGANIC ACIDS, AMINES, AND OTHER ORGANIC COMPOUNDS CAN BE SEPARATED WITHOUT ANY MARKED TAILING BY USING STEAM AS THE CARRIER GAS FOR GAS-SOLID CHROMATOGRAPHY. ACTIVATED ALUMINA SERVES AS A GOOD ADSORBENT FOR LOW-BOILING HYDROCARBONS, CHROMOSORB P FOR HIGH-BOILING HYDROCARBONS, DIATOMACEOUS FIREBRICK POWDER MODIFIED BY HYDROFLUORIC ACID FOR ALCOHOLS, KETONES, AND ESTERS, DIATOMACEOUS FIREBRICK POWDER CONTAINING LITTLE PHOSPHORIC ACID FOR CARBOXYLIC ACIDS AND PHENOLS, AND SINTERED MAGNESIA FOR AMINES. USE OF STEAM AS CARRIER GAS MAY CONSIDERABLY EXTEND THE APPLICABILITY OF GAS-SOLID CHROMATOGRAPHY. HIGH-BOILING MATERIALS, IN GENERAL, CAN BE ELUTED RATHER FAST WITH STEAM. WATER-CONTAINING SAMPLES CAN ALSO BE SUBJECTED TO THE ANALYSIS WITHOUT ANY DIFFICULTY. FOR EXAMPLE, EVEN THE SEPARATION OF 0.1 PPM C2-C7 FATTY ACIDS IN AQUEOUS SOLUTION CAN BE ACHIEVED IN THIS WAY.
