General contribution to the theory of retention index systems in gas-liquid chromatography : I. Pre-calculation of retention indices of alkanes on the basis of their molecular structures and thermodynamics in gas-liquid chromatography

Abstract

Results of the examination of several important problems connected with retention index systems, such as the additivity and pre-calculation of retention indices, the polarity of stationary phases expressed by retention indices and interaction factors on mixed stationary phases, are considered. This is intended to stimulate further constructive discussion, as happened with the relationship between molecular structure and retention index. It is hoped that this work will provide opportunities for researchers to extend their activities to other types of compounds and stationary phases and to consider the theory more deeply.
