FIELD: chemistry.
SUBSTANCE: stampyrine is transferred from a sample into a solution and stampyrine undergoes inverse voltammetric determination using a glassy-carbon indicator electrode with electrochemical accumulation at potential +1.2 V relative a saturated silver chloride for 120 s on the background of 0.1 mol/l sodium perchlorate in ethanol and then recording anode peaks with potential sweep at a rate of 0.05 V/s. Concentration of stampyrine is determined from the height of the peak at potential ranging from +1.0 V to +1.1 V using a calibration curve technique.
EFFECT: high sensitivity and rapidness of determining stampyrine.
