Abstract: The macrocyclic dioxopolyamine compounds, 1,4,7,10-tetraazacyclotridecane-11,13-diones were used as stationary phases with the aid of 3-(2-cyclooxypropoxyl)propyl-trimethoxy silane as a bridge in open-tubular capillary electrochromatography(OTCEC). The capillaries were etched by aqueous sodium before being coated. These modified capillaries had shown improved separations of neurotransmitters, isomeric dihydrobenzenes, isomeric nitrophenols and isomeric aminophenols in comparison with untreated capillaries.

Key words: Open-tubular electrochromatography, Macrocyclic dioxopolyamine, Bonded stationary phase
