Abstract
Apparatus and methods for the measurement of total organic carbon and total inorganic and organic content of water are described. A novel combination of an acidification module, and inorganic carbon removal module based on a carbon dioxide selective gas permeable membrane, and oxidation reaction system which incorporates in-situ generation of oxidizing agents, coupled with catalyzed photo-oxidation of organic compounds to form carbon dioxide; and a high sensitivity, conductometric detector employing a carbon dioxide selective gas permeable membrane permits on-line measurement of the total organic carbon content of water streams.
Claims12
Apparatus for the measurement of the total organic carbon of an aqueous sample in a sample stream comprised of:
- (a) oxidation reactor means for the conversion of organic compounds of an aqueous sample in a sample stream to carbon dioxide, said oxidation reactor means having an inlet and an outlet;
- (b) carbon dioxide membrane means for the extraction of said carbon dioxide formed in said oxidation reactor means into a deionized water stream, said carbon dioxide membrane means comprised of first and second chambers separated by a membrane, wherein said first chamber is in fluid communication with the outlet of said oxidation reactor means;
- and
- (c) conductivity and temperature measurement cell means in fluid communication with said second chamber for measuring the total concentration of the ionic species in said deionized water stream and the temperature of the deionized water stream.
