Different methods of electrophoretic determination bioactive substances in the form of their complexes with metal ions

Abstract

Possibility of determination of bioactive organic substances in the form of their complexes with
metal ions by the methods of capillary electrophoresis (CE): electroinjection (EIA) and electrophoretic
microanalysis (EMA); capillary zone electrophoresis (CZE) with injection of preliminary prepared
complex and with addition of one participant of complexation to the back ground electrolyte (BGE) –
metal cation or bioactive organic substances (biogenic amines, neurotransmitter amino acids, aromatic
hydroxyacids, cateсhins and others) were investigated.
