ASTM WK57075

    New Test Method for Total Sulfur in Aromatics by Monochromatic Wavelength Dispersive X-Ray Fluorescence Spectrometry

    (What is a Work Item?)

    Developed by Subcommittee: D16.04 | Committee D16 | Contact Staff Manager


    1. Scope

    This test method covers the determination of sulfur by monochromatic, wavelength-dispersive X-Ray fluorescence (MWDXRF)spectrometry in aromatic hydrocarbons, their derivatives, and related chemicals. This test method is applicable to samples with sulfur concentrations from x.xx mg/kg to xx mg/kg. Higher concentrations can be determined by quantitatively diluting the sample with a suitable solvent. In a preliminary study, the limit of detection was estimated to be x.xx mg/kg


    Sulfur in Aromatics


    1) It provides alternate means to perform Total Sulfur within D16. D7183 appears to be the most common Total Sulfur method within D16. 2) It utilizes the same technology as is used in the D7536 Chlorine test method. 3) It is able to detect sulfur well below the typical 1ppm max seen in most D16 standard specifications for aromatic materials (Benzene, Cyclohexane, et.) 4) The technology/instrument saves money in terms of cost and PMs that are typically required by the instruments used in D7183 and D7359.
