摘要
用新合成的两种侧链聚硅氧烷高分子液晶涂渍并交联成玻璃毛细管色谱柱,这种色谱柱具有很高的选择性和相当好的热稳定性,适用于分离3～5环多环芳烃异构体。
Four side-chain liquid crystalline polysiloxanes were synthesized and tested as gas chromatographic stationary phases.The liquid crystals were coated and in situ cross-linked on the glass capillary columns.The results showed that thei lquid crys-talline columns possessed high selectivity for se-paration of PAH isomers and high thermostability 13 PAHs of 3-5 rings were successfully separated on these columns
