U.S. EPA Method: 415.1 (Combustion or Oxidation)
Industry: Environmental
Instrument: Apollo 9000 Total Organic Carbon (TOC) Analyzer, Phoenix 8000 Total Organic Carbon (TOC) Analyzer

This method includes the measurement of organic carbon in drinking, surface and saline waters, domestic industrial wastes. The method is most applicable to measurement of organic carbon above 1 mg/1. Organic carbon in a sample is converted to carbon dioxide (CO2) by catalytic combustion or wet chemical oxidation. The CO2 formed can be measured directly by an infrared detector or converted to methane (CH4) and measured by a flame ionization detector. The amount of CO2 or CH4 is directly proportional to the concentration of carbonaceous material in the sample.
