Epsilon 4 Building materials

Improve your process efficiency through high-quality, low-cost elemental analysis.

X-ray fluorescence spectroscopy (XRF) has an important and well-established analytical role within the cement industry. It is used extensively for production and quality control for the elemental analysis of raw materials, alternative fuels and finished products.
Continuing Malvern Panalytical's successful and established line of benchtop spectrometers, Epsilon 4 provides state-of-the-art XRF analysis. The outstanding analytical performance of Epsilon 4 is comparable to floor-standing XRF instruments, with a much lower cost of ownership.
Discover the possibilities of XRF analysis and reduce your feedback time from hours to minutes by placing the XRF spectrometer next to the production line.

Value beyond compliance

X-ray fluorescence spectroscopy (XRF) has an important and well-established analytical role within the cement industry. In combination with the Eagon 2 fully
automatic fusion system, the Epsilon 4 complies with the latest cement testing methods of both ASTM C114-15 and ISO 29581-2 in only 10 minutes.
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

Accurate results

The unique high-performance, metal-ceramic X-ray tube, specifically designed and manufactured by Malvern Panalytical, ensures high-quality data and reliable results. Flexible voltage settings from 4.0 to 50 kV and a maximum current setting up to 3.0 mA optimize the performance across the periodic table.
Accurate results

Unattended operation

The combination of a 10-position removable sample changer with spinner enables the automatic processing of sample batches without the need for operator attention. Continuous rotation of the sample during measurement minimizes any errors caused by non-homogeneity or surface irregularities within individual samples and provides more accurate results.
Automatic transfer of data to a central location gives you access to the latest results.
Unattended operation

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.
