Journal ArticleDOI
Field-Deployable, High-Resolution, Time-of-Flight Aerosol Mass Spectrometer
Peter F. DeCarlo,Joel R. Kimmel,A. Trimborn,M. J. Northway,John T. Jayne,Allison C. Aiken,Marc Gonin,Katrin Fuhrer,Thomas Horvath,Kenneth S. Docherty,Doug Worsnop,Jose L. Jimenez +11 more
TL;DR: The development of a new high-resolution time-of-flight aerosol mass spectrometer (HR-ToF-AMS) is reported, which allows the direct separation of most ions from inorganic and organic species at the same nominal m/z, and the quantification of several types of organic fragments.
Journal ArticleDOI
Chemical and microphysical characterization of ambient aerosols with the aerodyne aerosol mass spectrometer
Manjula R. Canagaratna,John T. Jayne,Jose L. Jimenez,James Allan,M. R. Alfarra,Qi Zhang,Timothy B. Onasch,Frank Drewnick,Hugh Coe,Ann M. Middlebrook,A. E. Delia,Leah R. Williams,A. Trimborn,M. J. Northway,Peter F. DeCarlo,Charles E. Kolb,Paul Davidovits,Douglas R. Worsnop +17 more
TL;DR: A detailed discussion of the strengths and limitations of the AMS measurement approach is presented and how the measurements are used to characterize particle properties are reviewed to highlight the different applications of this instrument.
Journal ArticleDOI

TL;DR: A recently developed method to rapidly quantify the elemental composition of bulk organic aerosols (OA) using a high-resolution time-of-flight aerosol mass spectrometer (HR-ToF-AMS) is improved and applied to ambient measurements.
Journal ArticleDOI

TL;DR: In this article, an analysis of high resolution OA spectra was performed at the T0 urban supersite in Mexico City with a High-Resolution Time-of-Flight Aerosol Mass Spectrometer (HR-ToF-AMS) and complementary instrumentation.
Journal ArticleDOI
Airborne measurements of the spatial distribution of aerosol chemical composition across Europe and evolution of the organic fraction
William T. Morgan,James Allan,Keith Bower,Eleanor J. Highwood,Dantong Liu,Gavin R. McMeeking,M. J. Northway,Paul I. Williams,Radovan Krejci,Hugh Coe +9 more
TL;DR: In this paper, the spatial distribution of aerosol chemical composition and the evolution of the Organic Aerosol (OA) fraction are investigated based upon airborne measurements of aerosolic chemical composition in the planetary boundary layer across Europe.
