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.
Guaranteed performanceEpsilon 4 is a star-performing benchtop XRF instrument and is well suited for the analysis of additives and wear metals in fresh and unused lubricating oils. The benchtop XRF instrument provides a fast method for the analysis of lubricating oils without the need for sample preparation and use of chemicals.
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 yearsA low-drift X-ray tube and an automatic drift correction system give compliant results for years without the need for re-calibration. This results in a more efficient use of the system and less cost of calibration maintenance.
Fast and sensitive
Fast measurements are achieved by using the latest silicon drift detector technology that produces significantly higher intensities.
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.
Reduce helium consumption
The high performance of Epsilon 4 enables many applications to be operated in air atmosphere, without longer overhead time and costs involved for helium or maintenance of vacuum system. When measuring in air, low-energy X-ray photons characteristic of sodium, magnesium and aluminium, are sensitive to variations in air pressure and temperature. Built-in temperature and air-pressure sensors compensate for these environmental variations, ensuring excellent results whatever the weather.

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.
