| Research Abstract |
For evaluation of air quality such as secondary organic aerosols and photochemical oxidants, it is essential to know characteristics of productivity of organic nitrates (ONs) during the reaction of various volatile organic compounds (VOCs) with atmospheric radicals. In this study, we tried to establish a new method for measurement of ONs productivity based on a total ONs analyzer and the chemical perturbation technique. ONs productivities of a few VOCs were measured and relatively compared. Furthermore, quantitative determination of the branching ratio for ONs formation was successfully conducted. This method can be promising for improvement of the database of ONs productivities, especially for VOCs whose ONs productivities have not been reported yet.
