Accurate analysis of precious metals Pt, Rh and Pd and other elements in car catalytic converters

Catalytic converters are designed to remove toxic gases and pollutants from car exhaust gases. Therefore, they contain the precious metals Pt, Pd and Rh. When the car reaches end of life the converter is scrapped. The precious metals are recovered in a recycling chain comprising several different stakeholders, from scrap yards to toll refineries. Due to their high value, accurate analysis and processing of the precious metal content is critical to ensure maximum return in recycling. This application note shows a safe, easy and accurate method for providing data giving full insight in the composition of the to-be-processed converter.
