Epsilon 4 Food & environment

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

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.
