## Abstract Column selectivity is examined for a series of smectic liquid crystalline columns and is compared with methyl and C~18~ polysiloxane columns for the separation of polycyclic aromatic hydrocarbon (PAH) isomers. A set of extended and condensed solute probes is described that provides a se
The selectivity coefficients and retention ranges of isomeric hydrocarbons on various stationary phases were compared. The advantage of liquid crystals, used as shape-selective stationary phases in capillary gas chromatography for the separation of structural and geometric isomers and diastereoisome
