Chemical characterization of petroleum is a challenging task due to its inherently complex
nature. For example, crude oil is believed to have as many or more compounds than the …

Asphaltenes comprise the heaviest and least understood fraction of crude petroleum. The
asphaltenes are a diverse and complex mixture of organic and organometallic molecules in …

Molecular composition analysis of petroleum and alternative fuels has been considered as
one of the greatest challenges in analytical chemistry. The rapid development of Fourier …

The developments of high-resolution mass spectrometry and soft ionization technologies
have enabled the molecular characterization of petroleum fractions. However, quantitative …

Direct “dilute and shoot” mass spectral analysis of complex naturally-occurring mixtures has
become the “standard” analysis in environmental and petrochemical science, as well as in …

In this study, Fourier transform ion cyclotron resonance mass spectrometry (FT-ICR MS),
combined with quadrupolar detection (QPD), was applied for online liquid chromatography …

The current state-of-the-art analysis techniques for petroleum fractions has progressed
substantially during the past decade. This has helped to further improve the lumping …

Analytical techniques for chemical analysis of oil, oil photochemical and biological
transformation products, and dispersants and their biodegradation products benefited …

Hydrocarbon oxidation products (HOPs) formed from crude oil and diesel were formed from
laboratory simulated spills at four different periods (1, 4, 7, and 10 days) under …

Dissolved organic matter (DOM) is an ultracomplex mixture of organic compounds in the
land/ocean–atmosphere interface. Normally, polar compounds from DOM are hardly …
