FIELD: medicine.
SUBSTANCE: method for quantitative determination of phenibut in microcapsules using capillary electrophoresis involves an analysis in a quartz capillary with effective length of 0.5 m, internal diameter of 75 mcm, under the influence of an electric field using a leading electrolyte solution, followed by spectrophotometric determination of the reaction products, 10 mM solution of 10-aqueous sodium tetraborate with pH of 9.2 is used as the leading electrolyte, the analysis is carried out at a voltage of +20 kV, temperature of 30°C and detection wavelength of 193 nm.
EFFECT: increased accuracy of determination.
