化学键合固定相(键合相)是高效液体柱色谱技术发展的重大成就。虽然历史很短,但已引起了人们的注意。测定键合相性能的方法,国外已有报导。国内也做了许多工作。用红外光谱对键合相表面性质进行研究,国外已有报导,但用差热分析对键合相表面性质进行研究的报导作者还没见 Chemically bonded stationary phases (bonded phases) are major achievements in the development of HPLC techniques. Although the history is very short, it has drawn people’s attention. The method of measuring the performance of bonded phase has been reported abroad. A lot of work has been done domestically. The study of the surface properties of the bonded phase by infrared spectroscopy has been reported in foreign countries, but the authors who have studied the surface properties of the bonded phase by differential thermal analysis have not yet seen
