摘要
亲水作用色谱(HILIC)是近年来色谱领域研究的热点之一。本文围绕复杂体系样品中亲水性组分的分离分析,综述了国际上近年来发展的以HILIC为核心的多种液相色谱联用技术及其应用。简要介绍了HILIC的起源、定义、分离特点及其常用固定相;比较了HILIC和反相色谱(RPLC)的选择特性;针对不同层次的分离对象和分离要求,讨论了多种基于HILIC的液相色谱以及液相色谱-质谱联用技术的分离特点和适用范围。
Hydrophilic interaction chromatography(HILIC)is popular in the analysis of hydrophilic solutes in recent years.As a unique liquid chromatographic(LC)separation mode,it has not only been successfully utilized for the separation of target compounds from complex matrixes,but also been hyphenated with other separation modes,such as reversed-phase LC(RPLC),ion-exchange chromatography,and various HILIC,to increase the resolution and peak capacity for "entire-component" analysis of complex samples.Here we briefly review the origin and concept of HILIC,its retention behavior,and the frequently used stationary phases.After discussing the selectivity orthogonality between HILIC and RPLC,several application areas of HILIC are introduced,including HILIC tandem mass spectrometry(HILIC-MSn),on-line HILIC pretreatment,comprehensive two-dimensional HILIC-MSn and on-line hyphenation of HILIC and RPLC.With abundant references,HILIC has been proved to be a powerful analytical tool for hydrophilic and polar complexes.
