ABSTRACT:
Apparatus and methods for the measurement of total organic carbon, total inorganic carbon and total carbon of water are described. The ample is acidified and split into an inorganic carbon stream and a total carbon stream. The inorganic carbon in the inorganic stream is oxidized and both the organic and inorganic carbon in the total carbon stream is oxidized. The resulting carbon dioxide is measured in each stream using carbon dioxide sensors employing a gas permeable membrane dividing deionized water from the oxidized sample water and a pair of micro-conductivity and temperature sensors.
