Background

The Restriction on Hazardous Substances initiative (RoHS) has been in force for several years. 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 analyzer using indirect excitation and polarization, giving QA/QC processes the means for fast and simple screening and analysis of materials that must conform to RoHS and similar directives.
