Epsilon 4 Oils & fuels

Save thousands in oil and fuel production

Epsilon 4 can be used to save up to $190,000 in the production of oils and fuels. Compliant, repeatable and accurate elemental analysis is a given but additional value is generated in several parts in your refining operation:

  • the elemental analysis of crude oil to optimize and adapt refinery processes
  • the determination of low levels of chlorine for optimal desalting and corrosion control
  • the determination of low levels of S, Ni, V, Ca and Fe to prolong your catalysts' life and improve their performance 
  • and the analysis of the sulfur content during fuel production and blending

Analyses performed by Epsilon 4 comply with international test methods and regulations, like TIER 3, ISO 13032, ISO 20847, ISO 8754, ASTM D4294, ASTM D4929, JIS K2541-4, IP 336 and IP 496.

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 sulfur and other trace elements in fuels according to the latest ASTM, EPA, ISO, IP and JIS test methods.
Illustrated below are the significant added values achievable by Epsilon 4, which is just a single 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 complies with international test methods and norms, like TIER 3, ISO 13032, ISO 20847, ISO 8754, ASTM D4294, ASTM D4929, JIS K2541-4, IP 336 and IP 496.

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.

Epsilon software

Epsilon software is the XRF analysis software platform that is used with PANalytical’s range of Epsilon 1 and Epsilon 4 benchtop EDXRF systems.

Epsilon software


Omnian software enables users to achieve the best possible analysis when dedicated methods or certified standards do not exist.



Oil-Trace is a software package consisting of a suite of standards which enables users to perform accurate and reliable elemental analysis of liquids using WDXRF and EDXRF.


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.
