RoHS: Cr, Hg, Pb, Br and Cd in polyethylene

AppNote XRF1602: analysis of Cr, Hg, Pb, Br and Cd in polyethylene (RoHS)

Background

Measurement of Cr, Hg, Pb, Br and Cd in polyethylene (PE) is demonstrated for RoHS rapid screening by EDXRF. The Restriction on Hazardous Substances initiative (RoHS) limits the allowable amounts of the toxic elements chromium, mercury, lead, bromine and cadmium in plastics and consumer goods. Energy Dispersive X-ray Fluorescence (EDXRF) is an accepted analysis technique for the rapid screening by XRF and quantification of the hazardous element according to RoHS norms. To meet the industry needs, Rigaku offers the NEX DE VS analyzer with automatic collimators and camera for sample positioning and sample image, giving QA/QC technicians the means for fast and simple screening and analysis of materials that must conform to RoHS and similar directives.
