Evolution of alpha-pinene oxidation products in the presence of varying oxidizers: CI- APi-TOF point of view
نویسندگان
چکیده
Alpha-pinene oxidation was studied in the CERN CLOUD chamber under near atmospheric conditions using varying levels of different oxidizers (i.e., O3, HOx and NOx with differing gas mixture compositions) in the presence and absence of UV-radiation, SO2 and additional organic traces; ammonia (NH3) and dimethylamine (DMA). The oxidation products and their evolution due to aging in the chamber were studied using a novel CI-APi-TOF technique, with the nitrate ion (NO3 ) based chemical ionization (CI) scheme. We aimed to the results that would indicate how different oxidizing pathways lead to different product distributions in the product clusters detected.

Characterisation of tracers for aging of a-pinene secondary organic aerosol using liquid chromatography/negative ion electrospray ionisation mass spectrometry
Secondary organic aerosol (SOA) from the oxidation of a-pinene is a very complex and dynamic mixture containing products with a different chemical nature and physicochemical properties that are dependent on chemical evolution or aging processes. In this study, we focus on the chemical characterisation of major products that are formed upon a-pinene ozonolysis SOA and subsequent aging throughOH-...
