Manufacturer's Response

Thank you for your review. We appreciate your time for this. It’s good to read that you are overall happy with the Epsilon 4 instrument and its capabilities for your application. And we have to do better on the aftersales service in your area.

The instrument achieved a great level of results, the software requires work.


Average Rating 4.0

Application Area:

Analysis of trace elements within iron ore

The Epsilon 4 produced high quality results with a great level of reproducibility, and with a reasonable assay time for the very low detection limits required for the project. The major drawback on the system is the user interface; the instrument software is outdated, the calibration portion is not intuitive and does not connect with outside application such as excel. From an operations perspective, the software is adequate, though again not very intuitive. As the assay chamber is not separate from the sample carousel the instrument can not be loaded and unloaded during operation, which is a limiting factor for a high throughput project. As always, the quality of service from the Panalytical team was above reproach, they provided a great level of care and responsiveness to queries and any instrumentation faults.

Thank you for the review Omar. Good to hear that the Epsilon is easy to use.

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.

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.

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 a 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.
