介绍了超临界CO2条件下在线光谱检测技术的方法,并对其进行了比较。回顾了在线光谱检测技术的应用现状,并对目前在线光谱检测技术存在的问题及发展前景进行了分析和展望。
Supercritical CO2 is a very good medium which has been used to make sustain-released pharmaceutical and other products. In the conditions of supercritical, in situ spectroscopy is one of the most important methods. In this article, in situ spectroscopy methods were introduced and compared. At the same time, the applying of these techniques was reviewed. This article also analyzed the problems of the methods and looks into the applying future of them.
