Total Sulfur, weight %

Also an X-ray Fluorescence (XRF) method, the instrument for this particular procedure is calibrated from 25 ppm to 1 % by weight, making this a useful tool in providing an accurate amount of sulfur in fuel from 25ppm - 1% by weight. If lower detection is needed, ASTM D7039 can be used by Peak Petroleum to provide precise, accurate ppm levels of sulfur.
