ABSTRACT:
The invention relates to a method for determining total reactive sulfur in a crude oil or fraction thereof using a mass spectrometer or gas chromatograph and mass spectrometer. Selecting fragment ions characteristic of reactive sulfur species enables the quantitative determination of total reactive sulfur species. The use of a low resolution mass spectrometer allows the rapid determination of total reactive sulfur in field or remote locations where more sophisticated instruments are not available.
