Epsilon 4 Mining & minerals
Increase your process efficiency and recovery rate
X-ray fluorescence spectroscopy (XRF) has an important and well-established analytical role within the mining and minerals industry. It is used extensively for exploration, grade control, process monitoring and assuring that the composition of waste is within the limits of environmental norms and regulations.
Epsilon 4 benchtop spectrometers are used in mining operations, even at remote locations, for fast elemental analysis of ores, minerals and rocks. The combination of low infrastructural demands and the high analytical performance, enables quick determination of operation strategies in mining locations where utilities are limited.
Discover the possibilities of XRF analysis and reduce your feedback time from hours to minutes by placing the benchtop XRF spectrometer next to your mine or processing plant.
Value beyond compliance
X-ray fluorescence spectroscopy (XRF) is a safe, cost-effective and highly reliable method, that is well-established within the mining and minerals industry.
Using the Epsilon 4 in at-line mineral processing operations, offers quick and efficient steering in mineral beneficiation plants.
Illustrated below are the significant added values achievable by Epsilon 4, with 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.
Flexible wide-range oxide solution (WROXI)
Malvern Panalytical has developed a unique set of 19 synthetic, multi-element wide-range oxide (WROXI) standards. Together with Epsilon 4, WROXI can be used for the analysis of major and minor elements in fused beads. With the FP algorithm in the Epsilon software, the WROXI application can determine concentrations of up to 21 common oxides in a wide range of rocks, ores and minerals.
Automatic transfer of data to a central location gives you access to the latest results.
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.
