The analysis of mixtures of all stable C1 - C4 hydrocarbons has been studied by the gas-liquid (GLC), gas-solid (GSC), and gas-liquid-solid (GLSC) chromatographic techniques. A complete separation of all readily available compounds in the C1 - C4 range has been achieved by GLSC which has, so far, proved to be the only technique capable of solving this analytical problem in a practicable fashion. New packings for GSC and GLSC columns have been developed; in particular, a novel technique of dilution of active column packing with inert solid has provided excellent and rapid separation of the hydrocarbons and offers prospects of wider application. The dramatic effect of exposure of solid adsorbent to volatile liquids has been revealed by chromatographic analysis. The origins of this phenomenon have been sought and a variety of different physico-chemical techniques has been employed. The study of this phenomenon has provided evidence of an adsorptive mechanism not previously well documented. The effect revealed here may account for many of the reports in the literature of chromatographic irreproducibility of solid adsorbents. Further, the results indicate that such irreproducibility may be overcome. In consequence, it now seems likely that GSC and GLSC may find wider application than in the past.
