Glass capillary column with nematogenic liquid crystals as stationary phases for separating polycyclic aromatic hydrocarbons

Summary Use of the homologues and analogues of nematogenic liquid crystals of the type N,N-bis(p-methoxylbenzylidene)-,-bi-p-toluidine (BMBT) as stationary phases in glass capillary columns is described. These stationary phases are very useful for resolving closely related, rigid solute isomers of three-, four- and five-ring PAH. With these columns it is possible to achieve faster and more complete separation of PAH compared with packed columns with a liquid crystalline stationary phase.
