Capabilities of the electrochemical methods in the determination of narcotic and psychotropic drugs in forensic chemistry materials

A survey of the capabilities of electrochemical methods for the separation (capillary electrophoresis) and determination (amperometry, the versions of voltammetry, and potentiometry) of narcotic and psychotropic drugs and their metabolites, which are of interest in criminological practice, as the constituents of biological materials (hair, blood, and urine) and medicinal preparations is presented.
