Since July 2006 the EU directive EU 2002/95/EC for the “Restriction of Hazardous Substances” (RoHS) in electrical and electronic products excludes all non-compliant products from the market. All new products and production processes need to be monitored for the concentration of restricted substances, namely hexavalent Cr, Hg, Pb, Cd and Polybrominated Diphenylethers and Biphenylethers (PBDE and PBE). Ensuring that no limit is exceeded is a huge challenge for every manufacturer of electrical and electronic equipment.

Reliable, accurate and fast screening for the RoHS restricted elements

Reliable, accurate and fast screening for the RoHS restricted elements in all different kinds of materials is a daunting task. In practice X-ray fluorescence (XRF) analysis has proven itself as the perfect analytical tool for fulfilling the main requirements of the industry and service laboratories. The M4 TORNADO permits direct measurement of solid samples, even complete PCBs. With the lowest calibration effort, shortest time-to-result and highest cost effectiveness, the µ-XRF method employed by the M4 TORNADO is perfect for screening large numbers of samples in a short time. The IEC working group TC111, responsible for the industrial standardization of RoHS procedures, has ranked XRF as the best analytical tool for quantitative screening in RoHS (IEC 62321).
