The conditions for the identification and determination of L-arginine and L-proline by capillary zone electrophoresis without their preliminary derivatization have been optimized. The effect of buffer electrolyte pH, injection time, potential and temperature on determination of L-arginine and L-Proline have been investigated. The quantities of L-arginine and L-Proline were determined in amniotic fluid. The duration of analysis doesn-t exceed 15 minutes.
