European Union (EC) environmental legislation contributes towards a better environment. It has significant implications for many manufacturing companies in terms of marketing, design, manufacturing, and end-of-life recovery and recycling. The Directives on Waste Electrical and Electronic Equipment (WEEE) and the Restriction of Use of Certain Hazardous Substances (RoHS) require producers to recycle waste electrical/electronic equipment and remove certain hazardous substances.
Specifically, RoHS provides that new electrical and electronic equipment put on the market for the first time from July 1, 2006, should not contain certain heavy metal toxins, including lead (Pb), cadmium (Cd), mercury (Hg), and hexavalent chromium (Cr). Rigaku energy dispersive X-ray fluorescence (EDXRF) can help manufacturers comply with RoHS/WEEE by providing rapid elemental analysis.
NEX CG II benchtop spectrometer is powered by Rigaku's RPF-SQX Fundamental Parameters (FP) software, featuring Rigaku Profile Fitting (RPF) technology and Scattering FP. This robust software allows semi-quantitative analysis of almost all sample types without standards – and rigorous quantitative analysis with standards. Rigaku's Scattering FP method automatically estimates the concentration of unmeasurable low atomic number elements (hydrogen to fluorine) and provides appropriate corrections.
Calibration standards can be expensive and difficult to obtain for many applications. With RPF-SQX, the number of required standards are greatly reduced, significantly lowering the cost of ownership and reducing workload requirements for running routine analyses.
