Abstract
Adsorption effects accompanying gas-liquid partition chromatography were investigated for supporting materials of three types. Two kinds of plots were employed to characterize these effects: logarithm of rational retention volume (xVg) vs. molar composition of the liquid phase and the excess free enthalpy (ΔgE(m)) vs. molar composition of the mixed stationary phase, the second series of plots being derived from the first one. The experimental results formed the basis of an attempt to explain the behavior of solutes chromatographed on supporting materials of various surface areas.
