Epsilon 4 Food & environment
Trust your product quality
Growing populations increase the need for a better handling of our earth’s resources. The Epsilon 4, an energy dispersive X-ray fluorescence (EDXRF) spectrometer, is a powerful analytical tool to obtain useful elemental information to maximize crop growth and ensure product and environmental safety.
The latest advances in excitation and detection technologies in Epsilon 4 open possibilities for challenging applications that are traditionally performed by ICP and AAS. Switching from ICP to EDXRF significantly reduces the use of consumables, utilities and time.
Overview
Epsilon 4 is used to control nutrients in animal feed to keep cattle healthy and minimize manure greenhouse gasses. Other applications include the monitoring of elemental composition of particle matter in ambient air (EPA IO3-3) or of nutrients and salt content in food products. Soil and fertilizer can be analyzed to optimize growth conditions and to ensure the absence of toxic elements according to ISO 18227, ISO 15309 and ASTM C1255.
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.
Low running costs
- No need for expensive acids
- No need for liquid nitrogen
- No sample preparation, just place the sample directly into the spectrometer.
- Expensive standards (like air filters) are not destroyed after the analysis and can be re-used as quality control or validation samples.
- Low maintenance through high-quality X-ray tube and silicon drift detector
Accurate results
- Powerful deconvolution algorithm in Epsilon software ensures accurate results even when element peaks are overlapping in the XRF spectrum.
- Blank subtraction in Epsilon software provides flexibility and accuracy when analyzing air filters with different backing material.
- Continuous rotation of the sample during measurement minimizes any errors caused by non-homogeneity and provides more accurate 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.

Software
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.
Omnian
Omnian software enables users to achieve the best possible analysis when dedicated methods or certified standards do not exist.
Enhanced Data Security
Securing your data and satisfying regulators.FingerPrint
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.
