Epsilon 4 Polymers plastics and paints
Increase your polymer product consistency
Your customers demand superior consistency of your polymer performance and consumer safety regardless of production location. The Epsilon 4, an energy dispersive X-ray fluorescence (EDXRF) benchtop spectrometer, provides elemental analysis with superior repeatability and accuracy, satisfying your customer’s consistency demands.
Ease-to-use measurement procedures and limited utility requirements enables reproducible analysis close to production lines and across multiple production sites. The Epsilon 4 delivers reliable results for months without recalibration. Guaranteeing your product quality was never easier.
Focus on product quality and consistency
Illustrated below are places in the polymer production process where Epsilon 4 offers its added value to its users.
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.
Unique polymer application solutions
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.e
Low running costs
Epsilon 4 does not require the use of expensive acids, gasses and fume hoods, like in ICP and AAS. The only requirement is mains electricity and in some cases the use of helium to boost the sensitivity for light elements in the sample. Also, the individual components in XRF spectrometers are not exposed to friction or heat and therefore last for many years.
Measurements with Epsilon 4 are carried out directly on loose powders or end products, with little to no sample preparation. Since XRF is a non-destructive technique, the sample can also be measured subsequently by other analytical techniques, if required.
