Description	The separation of 17 %22common%22 underivatized amino acids was attempted by open tutular capillary electrochromatography (OT.CEC) in fused-silica capillaries coated with Rh(III) tetrakis(phenoxyphenyl)porphyrinate (Rh(III)TPP(m-OPh)4OAc) using sodium phosphate and Tris-phosphate buffers as background electrolytes (BGEs). The OT-CEC separation of amino acids was compared with that obtained by capillary zone electrophoresis in bare fused-silica capilaries using the same BGEs. The amono acids were not derivatized and the UV-absorption detection was set at 200 nm. Depending on the experimental condition at least 15 amono acids were separated. The best separations were obtained in a Rh(III)TPP(m-OPh)4OAc-coated capilllary in 50 mM Tris-100 mM phosphate buffer at pH 2.25. Separation of the critical triplet val-Ile-Leu was always at least indicated being better at higher BGE concentrations. Regarding the sensitivity of the method, Iower concentration limits of detection (LODs) inf the coated capillary were obta The separation of 17 %22common%22 underivatized amino acids was attempted by open tutular capillary electrochromatography (OT.CEC) in fused-silica capillaries coated with Rh(III) tetrakis(phenoxyphenyl)porphyrinate (Rh(III)TPP(m-OPh)4OAc) using sodium phosphate and Tris-phosphate buffers as background electrolytes (BGEs).
