Automotive catalytic converters contain the precious metals Platinum, Rhodium and Palladium. The exact amount of these elements is important for the recycling industry to determine scrap values.

The European Directive on End-of-Life Vehicles (ELV 2000/53/EC) has the real effect that a huge number of different automotive catalytic converters are now recycled. The value of these used catalytic converters depends on the amount of precious metals they contain, making it important for the recycling industry to be able to determine precisely the content of Platinum, Rhodium and Palladium.
