Elemental Analysis for Sulfur in Fuel

Determining sulfur content in fuels by EDXRF is one of the most cost-effective and efficient techniques for technicians and analysts. Systems are typically more affordable than other technologies, are easy to use, and require minimal or no sample preparation. Additionally, EDXRF helps you meet industry standards like analyzing sulfur in petroleum and petroleum products per ASTM D4294, ultra-low sulfur in diesel testing per ASTM D7220, and ultra-low sulfur in gasoline per U.S. EPA Tier 3 Fuel Standards.

Discover how EDXRF makes sulfur analysis in fuels quick and easy.
