METHOD FOR DETERMINING CATECHOLAMINE QUANTITY IN URINE Russian patent published in 2002 - IPC

FIELD: medicine. SUBSTANCE: method involves carrying out electrochemical catecholamine concentration from urine on the glass carbon electrode surface with following volt-ampere curves recorded under potential scanning velocity being equal to 20 mV/s and determining catecholamine concentration from analytic signal. Concentration is carried out on glass carbon electrode during 60 s under 0.1 V potential on the background of 0.1 N ammonium nitrate when determining catecholamine adrenalin. Concentration determination from analytic signal is carried out in 0.6 to 0.7 V potential range. Concentration is carried out on glass carbon electrode during 120 s under -0.3 V potential on the background of 0.2 N sodium hydrophosphate when determining catecholamine adrenalin. Concentration determination from analytic signal is carried out in 0.2 to 0.3 V potential range. EFFECT: accelerated analysis method. 3 cl
