ResumoThe development of laboratory-made electrochemical detectors of simple design with a glassy carbon working electrode employed with the conventional type and microbore high-performance liquid chromatographic (HPLC) columns is reported. The dependence of the detector response and performance on the eluent flow-rate, pump pulsation, applied potential, etc., is discussed. The detectors were used for HPLC, flow injection analysis and recording of constant depolarizer flow polarogams The application of the detectors to the analysis of hydroquinone, p-methoxyphenol and phenothiazine in acrylic monomers with detection limits of 10−7−−8mg is described
