Focus on product quality and consistency

The Epsilon 4 offers directly its value to producer of polymers, plastics and paints. Enable full traceability by fast and direct analysis throughout and close to production processes. Validate the quality of incoming raw materials and analyse the presence of additives, catalyst residues and toxic elements in final products. Malvern Panalytical unique calibration solutions ADPOL, TOXEL and RoHS supports its users to realize consumer safety and a consistent and high-end product quality and performance.

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.

The power of benchtop XRF

Unique polymer application solutions

Access to the right calibration samples is key in XRF. For the plastic & polymer industry we developed unique calibration solutions to accurately analyse for additives and catalyst residues (ADPOL), toxic elements (TOXEL) and to ensure RoHS compliancy (RoHS) in accordance with ASTM F2617 and IEC 62321-3-1.
Unique polymer application solutions

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.e
Fast and sensitive

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.

Low running costs

Non-destructive analysis

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.
