摘要
本文报道了3种新的聚硅氧烷侧链冠醚作气相色谱固定液,并涂渍成弹性石英毛细管柱,这种毛细管柱具有优良的色谱性能,它们具有柱效高,热稳定性好,选择性强的特点,适于分离各种异构体。
Three new kinds of poly (crown ether)siloxane as capillary gas chromatographic stationary phases are presented. The behavior of the capillary columns coated with these polymers was studied)and experimental result shows that these columns exhibited an excellent property. They possess a high efficiency, a good thermostability and a nice selectivity.therefore these columns are suitable for the separation of a variety of isomers separating difficultly on the other conventional stationary phases.
