毛细管气相色谱柱近年的发展

Recent advances of capillary gas chromatographic columns

简要地阐述了近几年毛细管气相色谱柱的发展和特点。GC的色谱柱制柱工艺是一个成熟的技术,所以在制柱工艺方面的研究不够活跃。近年新研究的固定相集中在常温离子液体和各种环糊精的衍生物。20世纪GC毛细管色谱柱柱工艺的研究主要在研究机构和学校中进行,而近几年GC毛细管色谱柱的研究和改进集中在色谱柱厂家进行,并立即成为商品柱。近年GC分析所用的色谱柱大都使用毛细管柱,并趋向于使用商品GC毛细管柱,所使用的商品色谱柱中,最多的是以含5%苯基的聚甲基硅氧烷色谱柱。

The recent advances and feature of capillary gas chromatographic columns were briefly described.Because of the field of GC column technology is still considered a mature science,it leads to relatively few research programs that are active in this area.In the research of stationary phases,the room temperature ionic liquids continued its development and the modified cyclodextrins were another project of GC stationary phases being studied.In last century the investigation of gas chromatographic columns were carried out in academies and universities,but in recent years these studies were accomplished in manufacturing plants and were quickly turned into market commodity.Today a lot of chromatographers prefer to use commercial capillary GC columns rather than the home-made ones.Most of commercial capillary GC columns used are those containing 5% phenyl polydimethylsiloxane.
