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.

The power of benchtop XRF

Guaranteed performance

Epsilon 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.
Guaranteed performance

Calibrated for years

A 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.
Calibrated for years

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.
Fast and sensitive

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.
