Analysing lube oils? Spending too much on calibration standards?

Whether you are producing high-performance base lubes or formulating custom blends for demanding environments, elemental analysis is essential. However, many commercial labs and R&D groups face challenges in meeting the performance and compliance requirements of modern lubricants, which often means complex calibrations and costly sets of standards that may not model your blends.

What if you could reduce standards requirements without compromising quality?

The Rigaku NEX CG II elemental analyser brings precision and simplicity in meeting the real-world demands for the analysis of lube oils. 

The NEX CG II provides: 

• Rapid, non-destructive multi-elemental analysis

• Powerful, easy-to-use Matching Library software

• Ensure compliance with multiple testing methods

• Easy operation for non-technical users and experts

• Low cost of ownership backed by a 2-year warranty

For compliance and quality control needs, sample prep is minimal, and the workflow is easy. And for multi-product facilities or fast-moving R&D teams, the NEX CG II is a game-changer.

Reduce Your Costs with Matching Libraries 

What sets the NEX CG II apart is the reduction of calibration standards requirements using its user-friendly Matching Library software. Commercial standards are expensive and may not represent your specific formulations. With the NEX CG II, you can create user-defined Matching Libraries based on actual in-house or assayed products. This not only saves time and costs but also improves the quality of results by aligning calibration directly with the products you analyse every day. You can easily tune your XRF for different oil families like engine, gear, or marine lubricants. By reducing the number of required standards and improving method specificity, Matching Libraries help you operate more efficiently and scale confidently across your product lines.

Meet Your ASTM D7751 Compliance Needs and More

The NEX CG II provides non-destructive qualitative and quantitative elemental analyses of sodium to uranium in almost any matrix, from ultra-low concentrations to high weight percent levels. It’s an indirect excitation EDXRF system using secondary targets rather than tube filters. This method reduces background noise, improves detection limits, and excels at complex applications with trace elements and variable base matrices. 

With the ability to analyse elements like Mg, P, S, Cl, Ca, Zn, and Mo, the NEX CG II can help you track additive concentrations to meet even the most stringent specifications. It’s well-suited for analysing additive elements in lubricating oils per ASTM D7751-16(2021). It also supports ASTM D6481-14(2019) for determining P, S, Ca, and Zn in lubricants.

Want performance, simplicity, and long-term value?

From routine compliance to advanced formulation, the NEX CG II helps you do more with fewer standards. Whether you're validating additive packages or developing the next generation of lubricants, Rigaku’s NEX CG II delivers dependable performance without unnecessary complexity.
