Polymers and plastics: analysis of RoHS restricted elements

Turnkey solution for accurate analysis of RoHS restricted elements (Cr, Br, Cd, Hg and Pb) in polymers

Manufacturers of plastics and polymers are obliged to meet RoHS regulations and ASTM F2617-08 international standards. This legislation defines the maximum allowable concentration for several restricted elements. X-ray fluorescence (XRF) spectroscopy is a powerful technique for proving regulatory compliance in the polymers industry.

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.

Expertise program: for XRF analysis of RoHS elements in Polymers and plastics

This Expertise program delivers a complete methodology from sample preparation to quality assurance for elemental analysis in polyolefins (all kinds of PP and PE, including iPP, HDPE, LDPE, mPE, ULMWPE etc.). It can be applied to Zetium, Axios, MagiX or Epsilon range systems. The following elements and concentration ranges are covered:

Elements ppm
As 0 - 145
Br 0 - 980
