Voltammetric identification of antiarrhythmic medicines using principal component analysis

Possibilities of voltammetry are considered as applied to problems of the identification of antiarrhythmic medicines from various producers using an electronic tongue based on glassy carbon electrodes modified by polyarylene phthalides. The electrochemical behavior of electroactive compounds in the composition of antiarrhythmic medicines was studied; the optimum conditions of recording voltammograms are found; and a method of the voltammetric identification of atenolol and propranolol using principal component analysis is proposed.
