تطبيق المواد البلورية السائلة في كروماتوغرافيا الغاز- السائل

Abstract

The objective goal of this research was concentrated on synthesize liquid crystalline which identified using FT-IR and the thermal crystalline characteristic were also investigated using the DSC and hot-stage polarized microscope technigues, the liquid crystalline, which showed great thermal stability over wide range of temperatures, has proposed to be applied as a stationary phase in gas liquid chromatography, some organic compounds which similar in atomic carbon number but different in geometrical stricture were sucessfully analyzed on the chromatography columns.
