The Certification of the Mass Fraction of the Total Content and the Aqua Regia Extractable Content of As, Cd, Co, Cr, Cu, Mn, Ni, Pb and Zn in Loam Soil, Certified Reference Material ERM®-CC141
This report describes the preparation and certification of a loam soil Certified Reference Material (CRM) ERM-CC141. The CRM was processed and certified by the European Commission, Joint Research Centre, Institute for Reference Materials and Measurements (IRMM), Geel, Belgium.
The CRM was prepared from a loamy soil with a natural level of metals. After being dried and milled, the resulting soil powder was put into amber glass bottles containing a minimum of 24 g of sample.
Certification of the CRM included testing of the homogeneity and stability of the material as well as the characterisation using an intercomparison approach.
The CRM has been certified for its total and its aqua regia extractable (according to ISO 11466) content of As, Cd, Co, Cr, Cu, Mn, Ni, Pb and Zn.
The main purpose of the material is to assess method performance, e.g. to check method performance and analytical results. As any reference material, it can also be used for control charts or validation studies.
