Determination of Sulfur in Fossil Fuels by Isotope Dilution Thermal Ionization Mass Spectrometry

Total sulfur is measured in 13 petroleum and 14 coal Standard Reference Materials by isotope dilution thermal ionization mass spectrometry. The total uncertainty, 95% confidence interval, for homogeneous materials such as oils is about .5%, whereas it is 1-4% for less homogeneous materials such as c...
