Background

The quality and grade of crude oil in part depends on the metal content as well as the sulfur content. Nickel and vanadium are the critical metals, as well as iron in some crudes and in residual oils and the metal content is especially important in the quality of bunker fuels. ASTM D8252 addresses the need to measure low levels of nickel and vanadium in crude to meet the NYMEX/CME specifications for light sweet crude oil futures contract concerning maximum allowable levels the Ni and V.

To meet the needs of the industry, Rigaku offers the NEX CG, a simple, versatile, an EDXRF analyzer ideally suited for the analysis of sulfur and metals in crude, residual oil and marine fuels. The NEX CG uses full 90° Cartesian Geometry Polarization monochromatic excitation giving superior light element performance as well as the metals.
