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

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...
