Capillary electrokinetic chromatography with polyethyleneimine as replaceable cationic pseudostationary phase - Influence of methanol and acetonitrile on separation selectivity

Abstract

The effect of methanol and acetonitrile, respectively, on the separation of neutral compounds is investigated in electrokinetic chromatographic (EKC) systems consisting of polyethyleneimine (PEI) as charged, polymeric, replaceable pseudos
