Epsilon 4 Lubricating oils
Value beyond compliance
Speeding up engine test while maintaining product quality are essential industry requirement for producers of lubricating oils. Compliance to international test methods like ISO and ASTM is an essential industry requirement for elemental analysis of lubricating oils. For the Epsilon 4 this mandated compliancy is merely the starting point, but where the instrument really shines is the additional value it brings for many other analytical tasks in the production of lubricating oils. For example:
- reduce errors of production by positive material identification
- faster and more accurate dosage of expensive additives
- supporting optimal blending efficiency of base oils and additives.
All analyses performed by Epsilon 4 comply with the latest test methods and norms, like ASTM D7751 and ASTM D6481.
Value beyond compliance
Epsilon 4 offers excellent performance for elemental analysis in different processes in refineries. This new and powerful benchtop XRF instrument is well suited for the analysis of additives and wear metals in lubricating oils according to the latest relevant international test methods. Illustrated below are the significant added values achievable by Epsilon 4, which is just one modest investment.
The power of benchtop XRF
Combining the latest excitation and detection technologies and smart design, the analytical performance of Epsilon 4 approaches that of more powerful and floor-standing spectrometers. Selective excitation and careful matching of the X-ray tube output to the capabilities of the detection system underlie the system’s outstanding performance.
Epsilon 4 complies with the latest test method ASTM D7751-15 for the analysis of magnesium, phosphorus, sulfur, chlorine, calcium, zinc and molybdenum in fresh lubricating oil by XRF.
Calibrated for years
Fast and sensitive
Unique detector electronics enable a linear count rate capacity to over 1,500,000 cps (at 50% dead time) and a count rate independent resolution typically better than 135 eV for better separation of analytical lines in the spectrum. This allows the Epsilon 4 spectrometer to run at full power and therefore realizes a much higher sample throughput compared to traditional EDXRF benchtop instruments.

Standards (Reference materials)
Epsilon software is the XRF analysis software platform that is used with PANalytical’s range of Epsilon 1 and Epsilon 4 benchtop EDXRF systems.
Omnian software enables users to achieve the best possible analysis when dedicated methods or certified standards do not exist.
A FingerPrint software module combined with an Epsilon EDXRF system is ideal for material testing when analysis speed is important but the actual composition is not of interest.
