|Title:||CCQM-K13.1 Subsequent Key Comparison: Cadmium and Lead in Sediment|
|Published:||February 01, 2006|
|Abstract:||CCQM-K13.1 is a Subsequent Key Comparison for Cadmium and Lead in Sediment conducted to provide the opportunity for two NMIs to demonstrate and document improvements in measurement capability achieved since the conduct of CCQM-K13, Amount content of Cadmium (cd) and Lead (pb) in sediment. The CCQM-K13 key comparison, completed in 2001, was a successor to CCQM-P15 (Cadmium and Lead content in sediment) study, and was performed to demonstrate and document the capability of interested National Metrology Institutes to measure Cd and Pb content in a sediment sample. The P15, K13, and K13.1 comparisons were activities of the Inorganic Analysis Working Group (IAWG) of CCQM, CCQM-P15 and K13 were coordinated by the Institute for Reference Materials and Measurements (IRMM, Geel, Belgium) of the Joint Research Centre (JRC) of the European Commission. The majority of the participants applied isotope dilution mass spectromety (IDMS) using various mass spectrometry techniques. External standard calibration was used by two participants for the Cd measurement and by one participant for the Pb measurement.|
