Abstract

A theoretical approach for description of distribution mechanism of molecules in phases used in
gas-liquid chromatography is developed. It is shown that surface of the polymer phase is “bended” by
adsorbate molecule, and under certain conditions the mechanism of “absorption by a macromolecule” is
realized with dilution in liquid phase after that. This effect is conditioned by macromolecular
conformational rearranging on the surface of stationary phase and formation of spherical cavern about
adsorbate molecule in result of their sufficiently long time interaction
