摘要
The determination of five aromatic amines was studied using capillary electrophoresis with pulse voltammetric detector. The D/A converter at an EVOC PLC-711B Card was used to generate the pulse electrode potential waveform. The A/D converter acquired the electrode current at the last one millisecond of every pulse. Good reproducibility and low limit were obtained. The results shown that pulse voltammetric detection has the advantages of elimination of charge current and direct identification of unknown chemicals.
