  • Design, characterization, and application of spectrometers for determination of low-level dissolved oxygen with small-volume sampling methodology

    Creator:
    Cakin, Defne
    Abstract:
    New analytical methods and instrumentation were developed for the determination of dissolved oxygen (DO) at low concentrations in water. The methods were based on monitoring the absorbance increase due to the oxidation of reduced indigo carmine (IC) by oxygen in the sample in different types of spectrometer cells. Spectrophotometer cells...

  • Coulometric determination of dissolved oxygen

    Creator:
    Healy, Michael Lyon
    Abstract:
    Many different aspects of the determination of dissolved oxygen by controlled potential coulometry were investigated to find a means of measuring the oxygen content of natural waters. Rapid sampling techniques, simplicity of operation, and rugged structural features were stressed. Cells were designed to operate by either internal electrolysis or external...
