Analytical Methods Used To Identify Nonmethane Organic Compounds in Ambient Atmospheres... 

The methodologies used to determine the concentration of nonmethane organic compounds (NMOCs) in ambient atmospheres are reviewed in this chapter. The symposium from which this chapter evolved was designed to provide analytical chemists who are not directly involved in atmospheric measurements with a brief summary of measurement technologies currently used for determining nonmethane organic compounds, with the hope that interest in developing improved measurement methods could be... 

Hundreds of chemical species are present in urban atmospheres. The gaseous air pollutants most commonly monitored are CO, O3, NO2, SO2, and nonmethane volatile organic compounds (NMVOCs), Measurement of specific hydrocarbon compounds is becoming routine in the United States for two reasons (1) their potential role as air toxics and (2) the need for detailed hydrocarbon data for control of urban ozone concentrations. Hydrochloric acid (HCl), ammonia (NH3), and hydrogen fluoride (HF) are occasionally measured. Calibration standards and procedures are available for all of these analytic techniques, ensuring the quality of the analytical results... 

In order to better understand nonmethane hydrocarbon involvement in the processes outlined in Figure 1, researchers are using sophisticated air-quality simulation models. These models usually require individual species information. Consequently, considerable effort is currently being directed toward the development and validation of analytical methods for measuring the concentrations of vapor-phase organic compounds in various environments.
