Monolithic columns have been employed in low pressure,fast and high efficient separation,for their many excellent characteristics.When applied to ion chromatography field,monolithic columns can achieve more effective analysis than traditional columns.Therefore,the method of ion chromatography based on monolithic columns attracts increasing interests.In this paper,the sorts of ion chromatography,classification of monolithic stationary phases,preparation ways of monolithic columns,performances and features of monolithic columns were introduced.The application of conventional monolithic columns in ion chromatography and the utilization of capillary monolithic columns in capillary ion chromatography were summarized according to the different assortments and properties of monolithic columns and ion chromatography,which included silica-based monolithic stationary phase and organic polymer-based monolithic stationary phase.The development of ion chromatography based on monolithic columns in the future was reviewed and prospected.
