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 …

In this review sample preparation strategies used for crude oil digestion in last ten years are
discussed focusing on further metals and non-metals determination. One of the main …

We describe complex organic mixture analysis by 21 tesla (T) Fourier transform ion cyclotron
resonance mass spectrometry (FT-ICR MS). Ultrahigh mass-resolving power (m/Δ m 50%> 2 …

Emulsions of oil droplets in water but more typically water droplets in oil are common in the
production, transportation, and refining of petroleum and related products. Emulsions of …

We describe the design and initial performance of the first 21 tesla Fourier transform ion
cyclotron resonance (FT-ICR) mass spectrometer. The 21 tesla magnet is the highest field …

This review focuses on recent advances in instrumentation, techniques, and applications of
the highest resolution mass analyzers (multipass time of flight (TOF), orbitrap, and Fourier …

Lignocellulosic biomass is a promising source of renewable energy and valuable chemicals.
It is abundant in several forms which may be pyrolyzed to give gases, condensates and …

Molecular characterization of asphaltenes by conventional analytical techniques is a
challenge because of their compositional complexity, high heteroatom content, and …

Asphaltenes and maltenes are defined operationally by solubility (in, eg, heptane).
Asphaltenes self-associate in solution and form putative nanoaggregates composed of …

Traditional tools for routine environmental analysis and forensic chemistry of petroleum have
relied almost exclusively on gas chromatography–mass spectrometry (GC-MS), although …
