Time-Resolved Chemical Composition of Individual Nanoparticles in Urban Air

Abstract: Chemical composition measurements of individual ambient nanoparticles were performed with a nanoaerosol mass spectrometer (NAMS) in Wilmington, DE, in May 2006. The atomic composition of each particle was determined from the relative signal intensities of multiply charged atomic ions in the mass spectra. The characteristics of particles with a mass-normalized-diameter of 25 nm analyzed on May 9 and 10, 2006, were studied in detail. Most of these particles contained carbon, nitrogen, oxygen, and sulfur. Almost … Show more

“…[30] Many studies have been performed to explore the enhancement effect of amines in nucleation in competition with ammonia. [31][32][33][34][35][36][37][38][39][40][41][42] In the past two decades, on-line single particle mass spectrometry has made significant contributions to the studies of ambient aerosols. [43] Using this technique, the size and composition of many individual particles can be determined simultaneously with good time resolution, allowing particle composition to be correlated with rapid changes in environmental conditions.…”

“…NAMS has been previously used to characterize ambient nanoparticles in an urban environment (Zordan et al 2008). In that study, particles emitted from motor vehicles were distinguished from photochemically generated particles on the basis of atomic composition, and the molecular compositions of both types of particles were inferred on the basis of knowledge of molecular species commonly present in ultrafine aerosol.…”

“…In this study, NAMS Zordan et al, 2008Zordan et al, , 2010Bzdek et al, 2011Bzdek et al, , 2012bBzdek et al, , 2013b) is used to obtain single particle mass spectra during NPF in Hyytiälä, Finland, from 21 March through 24 April 2011. NAMS provides a quantitative measure of nanoparticle elemental composition and in this study was set to analyze particles between 15 and 22 nm in diameter.…”

“…Note that NAMS does not quantitatively measure the hydrogen content, so it is not included in mole fraction determination. Deconvolution of overlapping signal intensities (C +3 and O +4 ; S +4 and O +2 ) was accomplished by the method of Zordan et al (2010). After deconvolution, the signal intensities for each element were summed, and the relative values were taken as the mole fraction of each element in the particle.…”
