摘要: A new buffer system for the separation of cations with capillary electrophoresis using indirect UV-detection is described. p-Aminopyridine can be used in wide pH-range between 3 and 10. High-speed separations positively charged non-UV absorbing ions are possible. Separation similar mobilities achieved by addition complexation reagents. The potassium ammonium possible either crown ether or at high pH-values. Transition metals separated adding 2-hydroxybutyric acid to buffer.
