Influence of capacity on the retention characteristics in Zwitter Ion Chromatography (ZIC) and ZICHydrophilic Interaction Chromatography (HILIC) onfour different sulfobetaine stationary phases

A number of covalently bonded zwitterionic stationary phases with inner quaternary amines and outer sulfonic acids in varying capacities was synthesized based on poly (styrene-DVB) particles by graft polymerization. The different spacer lengths and capacities are used as an investigative tool, fo...
