Historical Development of Liquid Crystalline Stationary Phases: An Overview

Abstract

Abstract:Nematic liquid crystals have shown particular selectivity and sensitivity as stationary phases for the separation of isomers having similar volatilities. Because of their unique selectivity towards rigid solute isomers, liquid crystal stationary phases were considered at one time to be a very promising class of materials that give the gas chromatographic separations a great deal of attention. In this overview, we present a brief historical view of the liquid crystal stationary phases development, which were successfully used in gas chromatography for separation of isomers.
