随着科学技术的发展，人们需要分离分析的样品越来越复杂，尤其是多肽、蛋白质类生物样品的复杂性使得单一模式色谱难以满足分离分析的要求。混合模式色谱因其独特的分离性能，可以在一次分离中获得与多维色谱相当的分离效果，而且可以避免多维色谱系统结构复杂、流动相兼容性差、分析时间长等问题，成为近年来的研究热点之一。混合模式色谱的研究重点是色谱固定相的设计与开发。混合模式色谱固定相包括反相／离子交换混合固定相、反相／亲水混合固定相、亲水／离子交换混合固定相、两性离子交换混合固定相及三相混合固定相。本文综述了近年来混合模式色谱填料的研究及应用进展，并对混合模式色谱及固定相的发展前景进行了展望。
With the development of science and technology,more and more complex samples like peptides and proteins need to be separated. It is difficult to separate them by single mode chromatography. Due to the unique separation character of mixed-mode chromatography,the same separation performance can be obtained in mixed-mode chromatography in one separation as multidimensional chromatography. And some disadvantages of multidimensional chromatog-raphy can be avoided in mixed-mode chromatography,such as the complexity of the system, the poor compatibility of mobile phases and the long analytical time. More and more attention is devoted to the mixed-mode chromatography in recent years. The focus on the mixed-mode chromatography is to design new structures of mixed-mode stationary phase. At present, mixed-mode stationary phases included reversed-phase/ion-exchange,reversed-phase/hydro-philic,hydrophilic/ion-exchange,zwitterionic and trimode mixed-mode stationary phases. The kinds of mixed-mode stationary phases are summarized and their features and applications in different fields are discussed in this review.
