Polycyclic Aromatic Hydrocarbons in Flames, in Diesel Fuels, and in Diesel Emissions

December 1, 2005
Author(s)
R Dobbins, Robert A. Fletcher, Bruce A. Benner Jr., S Hoeft
Numerous chemical analyses of gaseous and particulate samples from laboratory flames provide a library of data on the polycyclic aromatic hydrocarbons (PAH) species found in diverse flame types burning fuels consisting of pure gaseous hydrocarbons. Diesel

Polycyclic Aromatic Hydrocarbons in Flames, in Diesel Fuels, and in Diesel Emissions

January 1, 2005
Author(s)
Robert A. Fletcher, R Dobbins, Bruce A. Benner Jr, S Hoeft
Diesel fuels and emissions are composed of numerous hydrocarbon species. Combustion generated or pyrogenic polycyclic aromatic hydrocarbons (PAHs) derived from premixed and diffusion flames often consists of the most stable benzenoid PAHs. In contrast

Characterization of Surface Organic Components of Human Hair by On-Line Supercritical Fluid Extraction - Gas Chromatography/Mass Spectrometry: A Feasibility Study and Comparison with Human Identification Using Mitochondrial DNA Sequences

May 1, 2003
Author(s)
Bruce A. Benner Jr, J V. Goodpaster, J A. DeGrasse, L A. Tully, Barbara C. Levin
Hair is routinely collected at crime scenes for subsequent forensic analysis, typically involving inspection by microscope techniques to determine any distinguishing characteristics that might help associate the sample with an individual. Recent advances

The Existence of Precursor Soot in the Exhaust of Inverse Diffusion Flames

October 1, 2002
Author(s)
L G. Blevins, Robert A. Fletcher, Bruce A. Benner Jr, Eric B. Steel, George W. Mulholland
Knowledge of the chemical and physical structure of precursor soot is useful in the development of soot particle inception models. This paper examines the hypothesis that soot exiting an inverse flame is similar in chemical and morphological structure to

Distinguishing the Relative Contribution of Fossil Fuel and Biomass Combustion Aerosols Deposited at Summit, Greenland through Isotopic and Molecular Characterization of Insoluble Carbon

September 1, 2002
Author(s)
J F. Slater, Lloyd A. Currie, J E. Dibb, Bruce A. Benner Jr
Although the earth's polar regions are isolated from most industrial activity, combustion-generated particles from both fossil fuel and biomass burning impact the regions. Most efforts aimed at quantifying the input of combustion aerosols at Summit

A Critical Evaluation of Interlaboratory Data on Total, Elemental, and Isotopic Carbon in the Carbonaceous Particle Reference Material, NIST SRM 1649a

Lloyd A. Currie, Bruce A. Benner Jr, H A. Cachier, R Cary, J C. Chow, David L. Urban, T. I. Eglinton, O Gustafsson, P C. Hartmann, J I. Hedges, J D. Kessler, T Kirchstetter, D Klinedinst, George A. Klouda, J V. Marolf, C A. Masiello, T Novakov, A. Pearson, K M. Prentice, H Puxbaum, J G. Quinn, C. M. Reddy, H Schmid, J F. Slater, Stephen A. Wise, J Watson
A primary purpose of this report is to provide documentation for the new isotopic and chemical particulate carbon data for certified, reference and information values in Tables 12 and 13 of the Certificate of Analysis. Supporting this is a critical review
