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