“…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 .…”

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.

“…The complexity of hydrocarbon types increases with boiling point, and analyses of higher boiling petroleum fractions are frequently quoted on the basis of mass spectrometric hydrocarbon-type analyses [98,99]. The application of mass spectrometry to petroleum analysis has recently been reviewed by POWELL [100].…”
