A new stationary phase [bikis(2,6-di-O-pentyl-3-O-hex-6-enyl)-pentakis(2,6-di-O-pentyl-3-O-methyl)-β-CD-polysiloxane] was
synthesized and successfully applied in GC for the separation of chiral and achiral isomers. It possesses high column efficiency
and exhibits excellent separation ability for disubstituted benzenes. Some typical enantiomers and optical isomers are well
separated. The separation behavior of this new phase is characterized and discussed.
