Signal variation in single particle aerosol mass spectrometry
… security. One approach to such detection, bioaerosol mass spectrometry (BAMS), is currently under development at Lawrence Livermore National Laboratory. BAMS is a type of single particle aerosol mass spectrometry that rapidly records dual-polarity mass spectra of aerosolized micro-particles. …

Ion dynamics and aerosol mass spectrometry during atmospheric new particle formation
Eine große Zahl atmosphärischer Aerosolpartikel entsteht durch häufig auftretende sekundäre Neubildungsprozesse. Die aus Vorläufergasen entstehenden Partikel tragen zu einem großen Teil zur Gesamtpartikelanzahl in der Atmosphäre bei und haben somit einen weitreichenden Einfluss auf das Klima. Die …

Arctic Aerosol Sources and Continental Organic Aerosol Hygroscopicity
… in predicting the ultimate effect of aerosol on climate, the sources of atmospheric particles and their subsequent ability to turn into cloud droplets needs to be better understood. This thesis addresses two parts of this issue: the sources of Arctic aerosol and the hygroscopicity of …

Simulating the atmospheric primary and secondary organic aerosols
… This framework is used to simulate the organic aerosol formation, growth and composition in the eastern United States during the four seasons of the year. The model predictions are evaluated against daily average PM2.5 (particulate matter smaller than 2.5 μm) measurements taken throughout the …

Real time analysis of atmospheric single particles in urban environments using aerosol time of flight mass spectrometry
… fossil fuel combustion and 14% attributed to biomass burning. Furthermore, 79% of the EC was apportioned to local emissions and 21% to continental transport. The carbonaceous particle types were compared with quantitative measurements from other instruments, and while direct correlations using …

Investigating the Molecular Composition of Rainwater and Secondary Organic Aerosol using Ultra-High Resolution Mass Spectrometry
… complete molecular characterisation of organic aerosol. However atmospheric aerosol often has complex, mixed organic and inorganic composition and soft ionisation techniques that have been developed to ionise organic aerosol specifically, are susceptible to salt suppression effects and …
