electrochromatography of amino acids in systems with silica gel and water mobile phase
J. Planar Chromatogr. 29, 30-37 (2016). HPTLC and pressurized planar electrochromatography (PPEC) of 20 amino acids on silica gel with acetonitrile – buffer pH 3.2 (citric acid – disodium hydrogen phosphate 2.28:1.44) 1:1 for HPTLC and acetonitrile – buffer pH 3.2 4:1 for PPEC. PPEC separation was performed at a polarization voltage of 1.0 kV for 25 min. Detection by spraying with ninhydrin solution, followed by heating in a warm air stream.
