Adsorption Isotherms and Linear Gas-Solid Chromatography

Abstract

UNDER the title “Partition Isotherms and Gas-Liquid Chromatography,” Freeguard and Stock1 have reported that for all the systems studied by them, symmetrical elution peaks would be expected under normal gas-chromatographic conditions. Partition isotherms, however, when determined over partial pressures greater than those normally used in gas-chromatography, were found to be convex to the pressure axis.
