Abstract: An organic carbon analyzer system particularly adapted for the continuous analysis of raw sewage of a municipality. A gaseous transport is provided for carrying acidified liquid sewage including dispersed particulate matter through an elongated aeration chamber wherein carbon dioxide evolved from inorganic salts diffuses away from the sewage and into the gas. A second gaseous transport free of carbon dioxide and including an oxidizing agent then carries the sewage into a heated chamber having a tortuous interior surface which provides sufficient retention time to oxidize organic carbonaceous materials of the sewage resulting in a second evolution of carbon dioxide. An analyzer provides a continuous reading of the concentration of the carbon dioxide produced in the heated chamber.
