Development of Liquid Crystalline Stationary Phases for Liquid and Gas Chromatographic Separations
View Published Articles →01About This Special Issue
This Special Issue welcomes original contributions of fundamental research in the field of the theory and practice of Liquid Crystalline Stationary Phases for chromatographic separations.Authors may focus on short reviews of related topics, in addition to Articles.
Increasing attention has been focused on important pollutants introduced into the environment through the discharge of industrial waste and the decomposition of various pesticides. The determination of isomeric mixtures by ordinary stationary phases presents some difficulties, since these isomers have similar boiling points and polarities. The selectivity shown by Liquid Crystal phases is a consequence of the high degree of molecular order found in the liquid crystal mesophases. This selectivity is dependent on several factors including molecular shape, polarity and the flexibility of the solute molecule.
Chromatography is a very useful method for the direct separation of isomers. However, many years ago, commercially available Liquid Crystals were limited.
This issue provides an excellent platform for developing novel methods in Liquid Crystalline organic syntheses. In addition, their applications as stationary phases in gas and liquid chromatography for the separation and analysis of various isomers and enantiomers.

Historical Development of Liquid Crystalline Stationary Phases: An Overview
Issue: Volume 3, Issue 5-1, October 2015Pages: 7-10Received: 23 April 2015Accepted: 24 April 2015Published: 9 May 2015Abstract: 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 chromatog...
