EDXRF / XRF for Machinery Lubricants and Metalworking Fluids (MWFs)

Measure & Monitor Phosphorus, Sulfur, Chlorine, and More

Rapid Elemental Analysis of Phosphorus in Phosphate Esters Based Lubricants

For years phosphate esters have been used in industrial and consumer products because of their fire-resistant and anti-wear properties. These products are mostly used for applications with a higher chance of heat friction, sparks, or flames happening in or near the machine. Phosphate esters are commonly used in lubricants, hydraulic fluids, and lubricant additives.

Proper and safe operation of machinery depends on specific formulations, and users of these types of products must routinely monitor the fluids in use. Energy dispersive X-ray fluorescence (EDXRF) is a fast, simple method to solve these analytical needs. Users can quickly measure phosphorus in machinery lubricants for in-service testing, as well as R&D and other uses.

Multi-element Versatility – Measure Phosphorus, Sulfur, Chlorine, and More

All Rigaku EDXRF systems are multi-element analyzers. Rigaku EDXRF benchtops offer exceptional versatility by giving users a fast, reliable way of measuring phosphorus, sulfur, chlorine, and more – all with one instrument.

Quality control and quality assurance during the production of metalworking fluids and lubricants are essential. Rigaku EDXRF instruments are excellent tools for monitoring and controlling the elemental composition of fluids to ensure optimum performance. They are compact and easy to use, ideal for non-technical operators, yet powerful enough for expert use in commercial labs and R&D facilities developing new formulations.

Benchtop EDXRF Analyzers for Machinery Lubricants NEX QC

To achieve reliable quality control, we offer the NEX QC Series benchtop EDXRF analyzers. NEX QC Series analyzers combine superior performance capabilities with affordability. They deliver rapid qualitative and quantitative elemental analyses of sodium (Na) through uranium (U) in a wide variety of sample types. The intuitive touchscreen interface and built-in printer make these instruments easy to use and convenient. They are available in either a NEX QC or NEX QC+ model for more demanding applications or for situations where analysis time is critical.

For complex lubricants, we offer the NEX CG II. Using advanced Cartesian Geometry EDXRF, NEX CG II achieves the lowest limits of detection — even in challenging sample types. This spectrometer is compact and features powerful and easy-to-use Matching Library software. Commercial standards can be expensive and may or may not model your blends. With user-definable Matching Libraries, you can easily match your XRF to your specific formulations.
