Scientists have developed a way to isolate emulsion-causing petroleum compounds. The technique may help lower energy costs for both oil companies and consumers.
A young chemist studying fracking fluid talks about what it's like when science hits close to home.
Used to perform complex chemical analysis, this magnet offers researchers the world's highest field for ion cyclotron resonance (ICR) mass spectrometry.
State-of-the-art ion cyclotron resonance magnet system offers researchers significantly more power and accuracy than ever before.
The explosion of the Deepwater Horizon oil rig in April 2012 resulted in the release of ~5 million barrels of crude oil into the Gulf of Mexico ecosystem, a fraction of which washed ashore onto Gulf beaches. We compare the detailed molecular analysis of hydrocarbons in oiled sands from Pensacola Beach to the Macondo wellhead oil (MWO) by Fourier transform ion cyclotron resonance mass spectrometry to identify major environmental transformation products of polar, high molecular weight petrogenic material from Pensacola Beach.
Atmospheric pressure photoionization (APPI) Fourier transform ion cyclotron resonance mass spectrometry (FT-ICR MS) provides ultrahigh resolving power (m/Δm50% > 1,000,000 at m/z 500) and sub-ppm mass error (50 ppb) required to identify nickel porphyrin isotopes for unambiguous elemental composition assignment. We also report the first simultaneous identification and categorization of both vanadyl and nickel porphyrins in the same sample, without prior sample fractionation.
The MagLab and the Bruker Corporation have installed the world’s first 21 tesla magnet for Fourier Transform Ion Cyclotron Resonance (FT-ICR) mass spectrometry.
McKenna specializes in examining petroleum that is particularly difficult to refine. She’ll discuss the nature of oil and the 2010 BP spill in the Gulf of Mexico.
Traditional tools for routine environmental analysis and forensic chemistry of petroleum have relied almost exclusively on gas chromatography-mass spectrometry (GC-MS), although many compounds in crude oil (and its transformation products) are not chromatographically separated or amenable to GC-MS due to volatility. We apply ultrahigh resolution Fourier transform ion cyclotron resonance (FT-ICR) mass spectrometry to identify compositional changes at the molecular level between native and weathered crude oil samples and reveal enrichment in polar compounds inaccessible by GC-based characterization.
