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 15 synthetic, multi-element wide-range oxide (WROXI) certified reference materials (CRM). 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 11 common oxides in a wide range of rocks, ores and minerals.

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.

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.
