“…The recent success of FTICR MS in the petroleum field derives in large part from recent advances in ion-source technology. Generation of odd-electron molecular ions from both electron impact and field desorption/field ionization (FD/FI) sustained petroleum mass-spectral analysis for decades (16)(17)(18)(19), and those techniques have been successfully coupled to FTICR mass spectrometers (20 -24). However, extensive fragmentation of aliphatic hydrocarbon chains and the need for highly volatile analytes severely limit application of electron ionization to petroleum.…”

“…7,8 Low-resolution mass spectrometry (LRMS) methods, developed prior to the development of modern chromatographic methods, successfully allowed for the analysis of hydrocarbon compound types in gasoline, 9 lower distillate boiling ranges, 10 gas oil and higher distillate boiling ranges. [11][12][13][14][15][16] The methods provide quantitative information (i.e., relative amounts normalized to a total of 100%) about groups of chemical compounds summarized according to the degree of hydrogen deficiency, as reflected by the Z number (Z = 2, 0, À2, ,…) in the general formula for hydrocarbons C n H 2nZ . [17][18][19] The relative amounts of compound types such as paraffins (Z = 2), one-ring cycloparaffins (Z = 0), alkylbenzenes (Z = À6), etc, are used for quality control and monitoring of the effects of the different processing parameters.…”

The need to obtain detailed chemical information about heavy petroleum fractions, where the usefulness of chromatographic separation techniques is limited, has been addressed by using high resolution mass spectrometry (HRMS). A magnetic sector mass spectrometer was used for the experiments. The instrument meets the mass and dynamic range criteria for the analysis of compounds in complex hydrocarbon fractions, but not the resolving power needs for the separation of overlapping mass doublets. A simple and fast method has been developed that permits the calculation of the relative amounts of the ion species in overlapping mass doublets by consideration of the unresolved peak abundance and the difference between the theoretical and measured masses. The exhaustive determination of hydrocarbon compound type distributions is achieved by the sequential comparison of the theoretical masses of compounds with a given formula against those measured in the mass spectrum.

Sulfur heterocycles are found in low concentrations in most coalderived liquids and shale oils, and therefore, isolation of the heterocyclic sulfur fraction is necessary for individual compound Identification. In this report, a new methodology for the isolation and subsequent separation and identification of sulfur heterocycles is described and applied to selected coal liquids and shale oils. Identification was accomplished by sulfur-selective flame photometrk detection and comparison of mass spectral and chromatographic retention data of mixture components with standard reference compounds. Chromatographic retention data for 32 standard sulfur heterocycles were determined.
