Measurement of VOC reactivities using a photochemical flow reactor
Article Abstract:
Proponents of Airtrak 2000 decided to launch an enhanced version of the air monitoring instrument in an attempt to provide a more accurate and efficient tool for analyzing the reactivities of volatile organic compounds (VOC), or chemicals that contribute to the formation of smog in urban areas. The tool advocates the use of a flow reactor system that allows users to evaluate the steady-state condition of VOCs so that the early stages of smog formation are comprehensively analyzed. Results gathered from such an approach yield virtually the same measurements when compared to static chamber techniques.

Measurement of VOC reactives using a photochemical flow reactor
Article Abstract:
Volatile organic compounds (VOCs) reactivities are measured using Airtrak 2000, a commercial ambient air monitoring tool modified to function as a photochemical flow reactor. The flow reactor was utilized to measure the absolute and incremental reactivity of 18 single test VOCs and the incremental reactivity of six multicomponent VOC. With a flow system, a steady-state condition is established, representative of early stages of the smog forming process in the atmosphere. The flow system also allows monitoring of changes in the background chamber reactivity.

Atmospheric chemistry of HC(O)F: reaction with OH radicals
Article Abstract:
Research investigated atmospheric oxidation of hydrofluorocarbons (HFC) to advance knowledge of their environmental suitability as chlorofluorocarbon substitutes in industrial production. The study assessed the reaction of hydroxyl (OH) radicals with HC(O)F. Results indicated that the environmental impact of atmospheric oxidation of HFCs was insignificant.
