Scope

This standard specifies inductive coupled plasma-optical emission spectrometry (ICP-OES)
and inductive coupled plasma-mass spectrometry (ICP-MS) for the determination of platinum (Pt),
palladium (Pd) and rhodium (Rh) loading in the vehicle-used ceramic catalytic converters.
This standard is applicable to the determination of Pt, Pd and Rh loading in catalytic converters
with cordierite honeycomb ceramics as the carrier and precious metal as the active constituent.
Weigh 1g sample before digesting and scaling it to 100mL; then, analyze and determine, by
ICP- OES, the detection limit and lower limit which are 5μg/g and 20μg/g respectively; if by
ICP-MS, the detection limit and lower limit are 0.005μg/g and 0.02μg/g respectively.
