TL;DR: In this article, an overview of the atmospheric degradation mechanisms for SOA precursors, gas-particle partitioning theory and analytical techniques used to determine the chemical composition of SOA is presented.
Journal ArticleDOI

Magda Claeys,Bim Graham,Gyorgy Vas,Wu Wang,Reinhilde Vermeylen,V. A. Pashynska,Jan Cafmeyer,Pascal Guyon,Meinrat O. Andreae,Paulo Artaxo,Willy Maenhaut +10 more
TL;DR: Detailed organic analysis of natural aerosols from the Amazonian rain forest showed considerable quantities of previously unobserved polar organic compounds, which were identified as a mixture of two diastereoisomeric 2-methyltetrols: 2-methylthreitol and 2- methylerythritol, which can be explained by OH radical–initiated photooxidation of isoprene.
Journal ArticleDOI
Mass spectrometry in the structural analysis of flavonoids
Filip Cuyckens,Magda Claeys +1 more
TL;DR: A review of currently available mass spectrometry methodology used in the structure elucidation of flavonoids is presented and sample preparation, liquid chromatographic/mass spectrometric analysis and tandem mass Spectrometric procedures for the characterization of flav onoid aglycones, O-glycosides, C-glyCosides and acylated glycosides are considered.
Journal ArticleDOI
Chemical composition of secondary organic aerosol formed from the photooxidation of isoprene
Jason D. Surratt,Shane M. Murphy,Jesse H. Kroll,Nga L. Ng,Lea Hildebrandt,Armin Sorooshian,Rafal Szmigielski,Reinhilde Vermeylen,Willy Maenhaut,Magda Claeys,Richard C. Flagan,John H. Seinfeld +11 more
TL;DR: The first evidence of particle-phase esterification reactions in SOA, where the further oxidation of the isoprene oxidation product methacrolein under high-NO(x) conditions produces polyesters involving 2-methylglyceric acid as a key monomeric unit.
Journal ArticleDOI
Organosulfate formation in biogenic secondary organic aerosol
Jason D. Surratt,Yadian Gómez-González,Arthur W. H. Chan,Reinhilde Vermeylen,Mona Shahgholi,Tadeusz E. Kleindienst,Edward O. Edney,John H. Offenberg,Michael Lewandowski,Mohammed Jaoui,Willy Maenhaut,Magda Claeys,Richard C. Flagan,John H. Seinfeld +13 more
TL;DR: Several of the organosulfates of isoprene and of the monoterpenes characterized in this study are ambient tracer compounds for the occurrence of biogenic SOA formation under acidic conditions and reveal a viable mechanism for the formation of previously identified nitrooxy organosolfates found in ambient nighttime aerosol samples.
