|Abstract:||A comparison of high accuracy methods for the analysis of total sulfur in gas oils by three Metrology Institutes is described. The work contains a comparison of three different ascpects of the analysis: sample digestion, instrumental measurement and isotope dilution strategies. TIMS in combination with high pressure asher or Carius tube digestion has traditionally been used for such high accuracy analysis. However, this paper demonstrates that the faster, less laborious technique of ICP-MS in combination with microwave digestion is equally capable. Results from the comparison experiments show excellent agreement for fuel samples containing sulfur concentrations in the range 11 - 200 g•g-1.|
