Evaluation of high-field Orbitrap Fourier transform mass spectrometer for petroleomics

Abstract

The performance of the high-field Orbitrap Fourier transform mass spectrometer (FTMS) is evaluated in the context of petroleum sample analysis. Pertinent characteristics including resolving power, mass accuracy, and spectral dynamic range are tested with resin and maltene samples. Comparisons are made to the latest requirements for petroleum analysis by Fourier transform ion cyclotron resonance mass spectrometry (FT-ICR MS). The resolving power of the high-field compact Orbitrap mass analyzer (with a commercially provided resolution setting of 480,000 at 400 m/z) is found to be sufficient for adequate characterization of the oil fractions under consideration. We demonstrate that the high-field Orbitrap FTMS may provide acceptable mass accuracy, comparable to FT-ICR MS, when an in-house developed recalibration procedure is employed. Presented data show that the high-field Orbitrap FTMS is particularly suitable for the study of lighter oil fractions, preferably with low sulfur content. Comprehensive analysis of more complex crude oil samples requires a further, at least 2-fold, increase in resolving power.

Petroleum
Petroleum, also known as crude oil, or simply oil, is a naturally occurring yellowish-black liquid mixture of mainly hydrocarbons, and is found in geological formations. The name petroleum covers both naturally occurring unprocessed crude oil and petroleum products that consist of refined crude oil. A fossil fuel, petroleum is formed when large quantities of dead organisms, mostly zooplankton and algae, are buried underneath sedimentary rock and subjected to both prolonged heat and pressure.
Petroleum geology
Petroleum geology is the study of origin, occurrence, movement, accumulation, and exploration of hydrocarbon fuels. It refers to the specific set of geological disciplines that are applied to the search for hydrocarbons (oil exploration). Petroleum geology is principally concerned with the evaluation of seven key elements in sedimentary basins: Source Reservoir Seal Trap Timing Maturation Migration In general, all these elements must be assessed via a limited 'window' into the subsurface world, provided by one (or possibly more) exploration wells.
Oil refinery
An oil refinery or petroleum refinery is an industrial process plant where petroleum (crude oil) is transformed and refined into useful products such as gasoline (petrol), diesel fuel, asphalt base, fuel oils, heating oil, kerosene, liquefied petroleum gas and petroleum naphtha. Petrochemical feedstock like ethylene and propylene can also be produced directly by cracking crude oil without the need of using refined products of crude oil such as naphtha. The crude oil feedstock has typically been processed by an oil production plant.
