Abstract
The liquid chromatographic characteristics of polycyclic aromatic hydrocarbons on a recently reported liquid-crystal bonded phase were evaluated. The results clearly indicated that the material has a strong molecular planarity recognition capability because of its ordered bonded-phase structure. The recognition capability was dependent on mobile phase composition and column temperature. The behaviour can be explained by a so-called ‘slot-like’ structure used to describe retention of polycyclic aromatic hydrocarbons on polymeric octadecylsilica phases.
