Electrophoretic separation of biogenic amines (adrenaline,) Norepinephrine , Dopamine , Serotonin , Methanephrine , normetanephrine) in the modes of capillary zone electrophoresis and micellar electrokinetic chromatography with the introduction of complexing agents into the working electrolyte (18-craun-6; 4,13-diaza-18-crown-6; sodium dodecyl sulfate ion-pair reagent) and acetonitrile ; The technique of sample preparation of biological liquids (urine, serum and blood plasma) using solid-phase extraction on aluminum oxide and C18 reverse-phase sorbent ; was worked out The possibilities of different variants of concentration of biogenic amines were elucidated, which made it possible to reduce the limits of their detection by hundreds of times.
