Analysis of polycyclic aromatic hydrocarbons (PAHs) in air and water sources is a key part of environmental chemistry research, since most PAHs are well known to be associated with negative health impacts on humans. This study explores an approach for analyzing PAH mixtures with advanced nuclear magnetic resonance (NMR) spectroscopic techniques including high-resolution one-dimensional (1D Cited by: 1. Complex hydrocarbons are mixtures of various organic substances and are often classified as toxic and carcinogenic. They are regarded as phase-out substances in the PRIO tool. Examples of the substances with the most hazardous properties are benzene and polyaromatic hydrocarbons (PAHs).

Popl Published by Elsevier Science ().   Introduction. Complex mixtures of polycyclic aromatic hydrocarbons (PAHs) are produced from the incomplete combustion of fossil fuels, biomass 1,2, forest fires 3, volcanic eruptions 4, and hydrothermal processes 5 and consist of a wide variety of different PAH compounds, including parent PAHs (PPAHs), alkyl-PAHs (MPAHs), nitro-PAHs (NPAHs), oxy-PAHs (OPAHs), thio-PAHs (SPAHs), Cited by:

Hydrocarbon Types Analysis of Petroleum Distillates Mass spectrometry has been used in the quantitative analysis of petroleum distillates for more than half a century. Research at U.S. oil companies, which began during WW II, led to the development of the standard ASTM mass spectrometric methods, including D , D , D , D , and D. @article{osti_, title = {Improved resolution of hydrocarbon structures and constitutional isomers in complex mixtures using Gas Chromatography-Vacuum Ultraviolet-Mass Spectrometry (GC-VUV-MS)}, author = {Aerosol Dynamics Inc and Aerodyne Research, Inc., and Tofwerk AG, Thun and Isaacman, Gabriel and Wilson, Kevin R and Chan, Arthur W.

The SEC of polycyclic aromatic hydrocarbons (PAHs) in pure chloroform was observed to give longer elution times with increasing molecular mass, the opposite of the expected trend.
