Abstract
PACEPAC is the acronym for “production and certification of a road dust reference material for platinum, palladium and rhodium used in automotive catalytic converters” (Schramel and Lustig 1998). The overall objective of this project is to supply the needs of a suitable CRM for PGE analysis in environmental matrices. The motivation and background generally has to be seen in the increasing research activities on PGE emissions and especially in the unacceptable analytical uncertainty concerning the determination of PGE in the (naturally relevant) ultra-low (ng L-1 - µg L-1) concentration range. So far for platinum only three CRM are available, two based on ore matrices one as a grinded catalytic converter. Regarding the high concentrations of PGE and the matrices (nickel sulphide ore, nickel-copper-cobalt ore, cordierite) they are not very useful for the analysis of environmentally relevant samples. For PACEPAC a road dust, taken from the ceiling of a tunnel, is suggested to be the ideal matrix, as it provides the PGE in the chemical form and matrix in which they were emitted from the car-catalysts.
