scope:

This method covers the determination of total sulfur primarily in the range from 2 to 25 ppm in volatile, normally liquid organic materials (Note 1). The method may be extended to liquid materials with higher sulfur concentration and to viscous liquids and solids by using appropriate solvents. Samples should not contain more than 100 ppm of halogens, 2 ppm of barium, or 0.1 ppm of lead or appreciable ashforming substances.

NOTE 1-For the determination of total sulfur in liquefied petroleum gases see ASTM Method D 2784, Test for Sulfur in Liquefied Petroleum Gases (Oxy-Hydrogen Burner or Lamp).²

NOTE 2-To attain the quantitative detectability that the method is capable of, stringent techniques must be employed and all possible sources of sulfur contamination must be eliminated. In particular, cleaning agents, such as common household detergents which contain sulfates, should be avoided.
