中文摘要:
      层析是生物大分子分离纯化的一种重要手段,层析介质作为层析过程的关键的一部分受到了广泛的关注。层析介质的孔径结构对其分离纯化的效果有着显著的影响,因此探究层析介质的孔径结构至关重要。介绍了测定色谱介质孔径结构常用的方法,如:压汞法、氮气吸附法、小角X射线散射法、电镜扫描法(SEM和TEM)和逆体积排阻色谱法(ISEC)。重点阐述了ISEC法的基本原理和常用的探针类型,总结了ISEC法应用中的优点及不足,介绍了ISEC法的发展历史及其在国内外的研究现状。
英文摘要:
      Chromatography is one of the methods for separation and purification of biomolecules, and chromatography media has been widely concerned as a key part of the chromatography process. The pore structure of the chromatographic medium has a significant influence on its separation and purification efficiency. Therefore, it is very important to explore the pore structure of the chromatographic medium. This paper introduced several methods commonly used to determine the pore diameter structure of chromatographic media, such as mercury intrusion porosimetry, nitrogen adsorption, small angle X-ray scattering, transmission electron microscopy (TEM), scanning electron microscopy (SEM) and inverse size-exclusion chromatography (ISEC). The basic principle and common probe types of ISEC are described, the advantages and disadvantages in the application of ISEC are summarized, the development history of ISEC and its research advance are introduced in this paper.
