Better characterization and control of emissions from stationary sources of compounds under the Clean Air Act Amendments of 1990, Title III could be met by a continuous or semi-continuous measurement of total gaseous nonmethane organic carbon (TGNMOC). A search was initiated to identify detection systems for TGNMOC that are both simple to use and accurate. The measurement of oxygenated organic compounds was of particular interest since they are in many emission sources. Several detector systems, marketed as appropriate for TGNMOC measurement, were identified and evaluated in the laboratory. None of the detection systems evaluated would uniformly measure organic carbon in all types of organic mixtures. While some success was realized for many classes of organic compounds, oxygenated compounds could not be measured in a mixture of other organic compounds.
