Quantitative determination of sulfur by high-resolution graphite furnace molecular absorption spectrometry

► A new procedure to determine sulfur with high-resolution graphite furnace MAS via tin sulphide is described. ► Few interelement effects, low detection limit and easy-to-handle are some advantages of the procedure. ► The accuracy was verified by recovery rates and the determination of a certified reference material. ► It is possible to determine the total amount of sulfur of both inorganic and organic compounds.
