AB  - The is work presents the development of a flow injection system for differential pulse amperometry (DPA) for diazepam determination in the presence of oxygen. The thin flow cell consisted of the bare glassy carbon electrode, reference silver/silver chloride, and stainless steel as the auxiliary electrode. Electrochemical reduction of diazepam (DZP) was characterised by cyclic voltammetry. Azomethine reduction peak was used for DZP quantification. The detector response was linear in the range 20-250 mu mol/dm(3) of diazepam, with a calculated detection limit of 3.83 mu g/cm(3). Intraday and interday precision were 1.53 and 10.8%, respectively. The method was applied on three beverage samples, energetic drink, and two different beer samples, and obtained recoveries were from 93.65 up to 104.96%. The throughoutput of the method was up to 90 analyses per hour.

AB  - Diazepam belongs to the group of benzodiazepine drugs, and its consumption with alcohol enhances its sedative effect and absorption rate. That is why it is often used as “date rape drug” [1]. In our experiments we applied the flow injection system on diazepam determination on a bare glassy carbon electrode. The electrochemical determination of diazepam is based on reduction of the azomethine group yielding a dyhidrodiazepam. The single cathodic peak is caused by the reduction of diazepam by a two electron change. The reduction potential is highly dependent on pH value of the electrolyte, shifting to more negative potentials with higher pH [2].
