N2 - Nonmethane organic carbon (NMOC) is a measure of total organic carbon except for that from CH4. We recently reported the development of online instrumentation for continuous NMOC monitoring. This instrument, referred to as C-NMOC, uses a microsorbent trap in combination with a gas-sampling valve as the sampling interface. A conventional oxidation/reduction NMOC detector is used for quantitation. In addition to being an online concentrator and an injector, the microtrap serves as a separator that isolates NMOC from H2O, CO, CO2, CH4, and other background gases. Therefore, the C-NMOC is able to handle high concentrations of background gases commonly found in stack emissions and has detection limits in the ppb levels. This paper reports the results of field validation and testing of a C-NMOC analyzer at a coatings facility in the eastern United States. The instrument was able to monitor the process transients in real time, based on which corrective actions could be taken. It demonstrated good accuracy, high precision, and long-term stability.
