From crudes to final products, need elemental analysis that is fast, reliable, and cost-effective?

Are you monitoring crude oil, fuels, lubricants, or other petroleum products? If so, then you know elemental analysis is essential for product quality, process efficiency, and compliance. While traditional methods can meet these needs, it's often at the cost of time, budget, and flexibility.

Rigaku’s energy dispersive X-ray fluorescence (EDXRF) solutions are designed to help. Their benchtop and on-line systems deliver fast, reliable, and precise results while keeping running costs low and sample preparation minimal. With multi-element capability and versatile performance, Rigaku EDXRF makes it easier to monitor everything from heavy elements in crude to sulphur in fuels and metals in lubricants.

Benchtops for Every Facility

NEX CG II Series – All-in-one system for research and complex applications

• High-sensitivity analysis for trace elements and variable base matrices using indirect excitation with secondary targets
• Meets ULSD requirements per EPA Tier 3 and ASTM D7220, Mn at low and ultra-low levels per ASTM D5059 Part D, Pb per ASTM D5059 Parts C and A compliance using the Bi internal standard method, and the lowest Cl detection limits per ASTM D4929 Part C
• User-definable Matching Libraries, adapting to your unique needs and reducing calibration standards requirements
• Attractive choice for commercial labs and R&D facilities

Real-Time Process Control

Do you want to reduce sampling requirements for the lab? Rigaku also provides continuous on-line monitoring solutions for quality control and upset conditions.

• NEX XT – Total sulphur measurement from 0.04 to 6 wt% of crude, bunker fuel, fuel oils, and other highly viscous hydrocarbons, including residuums. Ideal for real-time blending operations for marine bunker fuel to pipelines, remote terminals, and refineries.
• NEX OL – Multi-element analysis for liquid process streams, supporting on-line control for cobalt, manganese, and bromine catalysts in PTA and catalyst recovery processes.

Whether in the lab or monitoring blending operations in real-time, Rigaku EDXRF systems provide the precision and reliability to keep your petroleum operations running smoothly and in compliance.
