XRF/XRD analysis for both upstream / downstream

Rigaku makes X-ray diffraction and X-ray fluorescence instrumentation for materials characterization and elemental analysis at every stage of the exploration, production and distribution process.

Sulfur and other elements in crude and fuels

Rigaku offers instruments for a variety of measurement protocols — including ASTM D2622, D7220, D4294, IP 532 as well as EN ISO 8754 & 20847. Rigaku NEX XT process analyzer for on-line measurement of sulfur for pipeline, blending and upgrading as well as bunker fuel blending for MARPOL compliance.

Additive packages for lubricating oils

Proper and safe operation of engines and machinery depends to a large degree on formulation of metallic additives. X-ray fluorescence (XRF) is a fast, simple method of analyzing lube oils for metallic composition. The XRF analytical technique is simple enough for use by non-technical operators, yet powerful enough for expert use in the R&D of new lube oil formulations.
