RoHS: chlorine and heavy metals in polyethylene

AppNote 1169: the analysis of Cl and the main elements Cr, Hg, Pb, Br and Cd in polyethylene governed by RoHS and similar directives are demonstrated here using the empirical method.


The Restriction on Hazardous Substances initiative (RoHS) has been in force for several years, limiting the allowable amounts of various toxic elements in plastics and consumer goods. In addition to the toxic metals, chlorine was added to the list in 2010. EDXRF is an accepted analysis technique for the rapid screening of the hazardous elements according to RoHS norms. To meet the industry needs for rapid screening using XRF, Rigaku offers the NEX QC EDXRF analyzer, giving QA/QC processes the means for fast and simple screening and analysis of materials that must conform to RoHS and similar directives.
