EDXRF Analysis of Chromium, Mercury, Bromine, Lead and Cadmium in Plastic Materials

Introduction

The Restriction of Hazardous Substance (RoHS) regulation has been implemented in the European Union (EU) as a facet of continuing environmental-related efforts. Consequently, it is getting more important to measure the hazardous elements in electrical and electronic equipments. EDXRF is frequently used as a screening method generally because it’s a nondestructive, rapid analysis technique that can measure various sample states (solid, powder, liquid, etc.). In this report, the sensitivity and repeatability of each hazardous element are determined by the EDX-720 using polyvinyl chloride (PVC) resin plastic material, which is used as electrical cable covering or chassis.
