Scope

This document is applicable to the determination of platinum, palladium, and rhodium content in metal carrier catalysts used for exhaust gas purification, both new and failed ones. The measurement range of flame atomic absorption spectrometry and inductively coupled plasma atomic emission spectrometry is platinum 5.00μg/g to 2000μg/g, palladium 5.00μg/g to 4000μg/g, and rhodium 2.00μg/g to 1000μg/g. Inductively coupled plasma emission spectrometry is used as the arbitration method.
