Ion-exchange electrokinetic capillary chromatography with starbust (pamam) dendrimers: a route towards high-performance electrokinetic capillary chromatography

The use of different generations of Starburst (pamam) dendrimers provides a new opportunity for ion-exchange electrokinetic capillary chromatography. The uniform surface charge density and the structural homogeneity of these macroelectrolytes provide a decrease of plate height in comparison with micellar electrokinetic capillary chromatography with cationic surfactants. In addition, the use of different dendrimer generations allows the separation selectivity to be modulated.
