In the atmosphere nighttime removal of volatile organic compounds is initiated by reaction with the nitrate radical. While OH plays a key role during the day and is overall the dominant oxidant in the troposphere, NO3 is one of the main oxidants during the night in addition to O3. Due to its formation from the reaction of NO2 with O3 the main source of NO3 is anthropogenic. Particulate nitrate can be of organic or inorganic origin. By the reaction between volatile organic compounds(VOC) and nitrate radical, organic nitrates are produced. They present secondary organic aerosols(SOA) and have influence on the air quality and climate change as well. While the formation of SOA through VOC oxidation by OH and O3 has been studied in numerous simulation chamber and laboratory experiments only few experiments report the SOA yields from the oxidation with NO3. This paper is about the organic nitrates and aerosol mas spectrometric methods, which is the most important techniques in the investigation of aerosols, in addition some graphs and examples from the real experiment will be discussed.
