Polarizable polysiloxane stationary phase containing a cyano unit attached to an aromatic side group for highly selective separation of H-bonding and aromatic analytes

Abstract

A new polarizable polysiloxane stationary phase containing a cyano unit attached to an aromatic side group, called CPPP [14.6% 3,4-bis(4-cyanophenyl)-2,5-diphenyl phenyl polysiloxane], was synthesized and used as a stationary phase for capillary gas chromatography (GC).
