As recent analytical techniques utilizing mass spectrometer in petroleum indnstry, high resolution and low resolution techniques anp also the technique using mass spectrometer with chromatograph, are reviewed in this paper.
High resolution technique with its ability to distinguish hydrocarbon overlap types, and sulfur, nitrogen, and oxygenated compounds, is being used to identify components of petroleum in more detail.
Low resolution technique is being activelyexamined by many researchers and the mass spectrometric methods as many as10 have been so far published from ASTM, Committee D-2.
Gas chromatograph-mass spectrometer combination technique is applied to various petroleum fractions, in place of the conventional time-consuming separations. This technique is also expected to develop increasingly as analytical method such as mass chromatography or mass fragmentgraphy.
