Abstract |
The Regional Air Pollution Study (RAPS) is collecting data on a regional scale for the evaluation and further development of air quality simulation models. A gas chromatography laboratory is operated to provide analyses for selected pollutants required to fully assess various submodels included in air quality simulation models. Hydrocarbons and other components of the atmosphere are analyzed in support of such studies as: (1) evaluation and development of submodels concerned with photo-oxidation reactions and transformations in the atmosphere; (2) evaluation of emissions inventory submodels; (3) tracking plumes; and (4) relationship between grid area measurements and grid point measurements. Specifically, atmospheric samples were analyzed for C1-C10 hydrocarbons, CO, NO + NO2, and total hydrocarbons. Additionally, analytical procedures were prepared and made operational for SO2, SF6, fluorocarbon -11, and fluorocarbon -12. The report describes the preparations and operations of a gas chromatography laboratory for analysis of atmospheric samples. The report includes a work plan, chromatographic sampling and analysis schemes, quality assurance tests, and air sample bag storage and contamination tests. |
