Background

In 2016 the U.S. EPA began phasing in Tier 3 gasoline, mandating the maximum allowable sulfur in gasoline to be 10 ppm (10 mg/kg). To this end, the EPA has established PBMS (performance-based testing requirements) similar to those for ULSD. The EPA allows any testing method that complies with the performance guidelines for accuracy and precision. To meet these needs, Applied Rigaku Technologies offers NEX CG II monochromatic EDXRF using Cartesian Geometry polarization. Ideal for ultra-low sulfur measurements such as Tier 3 gasoline and ULSD, NEX CG II is a multi-element analyzer capable of also measuring other applications throughout the petroleum industry. Powerful yet simple and intuitive to operate, the NEX CG II is an excellent tool for downstream analyses as well as midstream and upstream.
