Turnkey solution for accurate analysis of toxic heavy elements in polymers

X-ray fluorescence (XRF) spectroscopy is a powerful technique for both process control and regulatory compliance in the polymers and plastics industry. Reliable monitoring of the concentration of remaining catalysts helps to accurately control the polymerization process and ensures the maximum allowable concentration for several restricted elements is not exceeded.

XRF delivers important advantages compared to other elemental analysis techniques. Sample preparation is straightforward, with no dissolution required. Measurements are non-destructive and results are accurate and reproducible. Time-consuming and costly re-standardizations are unnecessary and the resultant data are consistent over long periods, saving time and money. Automated analysis reduces measurement times to a matter of minutes and efficient sample preparation methods support high throughput. User-friendly software allows routine analysis to be carried out by factory operators.
