ISOMER SPECIFIC ANALYSIS OF CHLORINATED DIOXINS AND OTHER COMPOUNDS BY GC AND GC-MS USING POLYMERIC LIQUID CRYSTAL STATIONARY PHASES

Abstract

The selectivities of three newly developed liquid crystal stationary phases were investigated and compared to those of a DB-5 column for a variety of environmentally important isomeric compounds. Attempts were made to relate the extent of solute shape discrimination to the magnitudes of the mesomorphic ranges, however it was difficult to conclusively evaluate the results.
