Cl and RoHS elements in polyethylene/Rigaku NEX CG EDXRF

Applied Rigaku Technologies has published Application Note #1033 that shows performance for the elemental analysis of Cl and elements regulated by RoHS in plastics. The application report shows the analysis of polyethylene using the Rigaku NEX CG EDXRF with Cartesian Geometry. Empirical calibration summary and detection limits are shown and instrument repeatability is demonstrated.

The Restriction on Hazardous Substances initiative (RoHS) limits the allowable amounts of various toxic elements in plastics and consumer goods. The latest extension to the RoHS regulatory guidelines is the measurement and control of total halogens, with particular emphasis on the chlorine content. EDXRF is an accepted analysis technique for the screening and quantification of the hazardous element according to RoHS norms. To meet the industry challenge, Rigaku offers the NEX CG EDXRF analyser using indirect excitation and polarisation, giving QA/QC processes the means for fast and simple screening and analysis of materials that must conform to RoHS and similar directives.
