Description:
The research summarized in this report investigated the application of a new electrochemical detector to the high-performance liquid chromatographic analysis of water for azo dyes. The detector is a computer-controlled device capable of being programmed to operate in many modes. Rapid-sweep square-wave voltammetry, the preferred mode of operation where applicable, was applied successfully to the azo dyes. For these compounds, the detector is more sensitive than a photometric detector, and the swept mode of operation is useful in resolving components not separated completely by the chromatographic column.
