Reliable Elemental Data Without the Wait or the Cost
Are you verifying sulfur content, tracking trace metals, monitoring for contaminants, or needing elemental composition for another type of application? If so, you are aware that having reliable elemental data is crucial for ensuring product quality, driving process improvements, meeting contractual agreements, and meeting regulatory compliance. While common testing methods provide reliable results, they often involve lengthy turnaround times, complex sample preparation, and higher overall analysis costs.
Energy dispersive X-ray fluorescence (EDXRF) has long provided a simpler and faster alternative for elemental analysis. Rigaku’s NEX Series EDXRF analyzers are built to meet the full range of petroleum industry needs, from everyday quality control to high-precision research and real-time process monitoring. Each system is engineered for ease of use, low cost of ownership, and compliance with international testing standards. They help you make confident decisions without delay and offer a more cost-effective alternative to other technologies.
From crude oil to finished fuels and lubricants, Rigaku’s analyzers help reduce costs and speed decision-making for a range of applications. Below is a quick comparison of these models.
Performance For Every Application
Rigaku EDXRF benchtops are built to handle petroleum applications, from verifying sulfur in fuels to detecting trace metals in crudes or lubricants. Users benefit from easy operation, robust designs, and software that simplifies calibration and method management.
For Everyday Quality Control — The NEX QC Series models provide dependable multi- element performance in a compact system with a built-in computer and printer. These analyzers are ideal for field labs, terminals, and production facilities that need rapid verification. Designed for simplicity and affordability, they deliver reliable results for sulfur and other key elements across a wide variety of petroleum products.
Complies with: ASTM D4294, D8252-19, ISO 13032, ASTM D5059.
Best suited for: Routine QA/QC, field verification, and in-plant checks.
For Labs that Need More Power — For facilities that demand greater flexibility and throughput, the NEX DE Series models combine high performance with streamlined operation. Their proprietary Matching Library software reduces standards requirements, and the VS option offers small spot analysis for in- plant forensics. These systems easily handle sulfur, chlorine, nickel, vanadium, and other critical elements.
Complies with: ASTM D4294, D8252-19, ISO 13032, ASTM 5059, ASTM D4929 Part C.
Best suited for: Refineries, midstream labs, and QA teams requiring fast, repeatable precision.
For Research and Trace-Level Analysis — For complex samples and ultra-low detection limits, the NEX CG II Series uses indirect excitation with secondary targets to achieve exceptional sensitivity across variable matrices. This makes them ideal for R&D, contract testing, and advanced
QA environments, where they can analyze everything from trace metals to additives. Custom Matching Libraries can be built directly within the software, saving time and reducing calibration standards costs.
Complies with: EPA Tier 3 and ASTM D7220 for ULSD sulfur, ASTM D5059 for manganese and trace lead, and ASTM D4929 for trace chlorine.
Best suited for: Research labs, commercial testing facilities, and advanced QA/QC environments.
Real-Time Monitoring
In continuous operations, reducing laboratory sampling can save both time and cost. Rigaku’s on-line analyzers extend elemental analysis to the process line. These systems help you identify upsets sooner, maintain
tighter control, and ensure every product stream stays within specification.
Sulfur Measurement — The NEX XT provides continuous total sulfur analysis from 0.04 to 6 wt% in various petroleum streams, including crudes, bunker fuels, and residuums. It’s ideal for refineries, blending operations, pipeline monitoring, and storage terminals where uptime and reliability are critical.
Multi-Element Process Analysis — For on-line, multi-element monitoring of liquid streams, the NEX OL offers simultaneous measurement of elements such as cobalt, manganese, and
bromine. It is well-suited for PTA production and catalyst recovery processes.
