New analytical possibilities of amperometric detection in high-performance liquid chromatography

It is demonstrated that sugars can be determined with high sensitivity by high-performance liquid chromatography (HPLC) with amperometric detection using domestic instruments. Optimal conditions of the detection of catecholamines were selected; obtained detection limits provide the determination of these compounds in biological fluids. Conditions of the simultaneous separation of most familiar narcotics by HPLC on one column with high precision and low detection limit were optimized.
