Description
|
ERM-EC680k and ERM-EC681k. They replace the exhausted predecessors, ERM-EC680 and ERM-EC681. The CRM was prepared from a low-density polyethylene (LDPE) granulate spiked with inorganic pigments (As2O3, Green 36, ZnS/CdS, Green 7, Cr2O3, PbCrO4/PbSO4, HgS, Sb2O3, SnO2).
Certification of the CRM included testing of the homogeneity and stability of the material as well as the characterisation using an intercomparison approach.
The new CRMs have been certified for their content of As, Br, Cd, Cl, Cr, Hg, Pb, S, Sb and indicative values have been established for Sn and Zn. Additional information about acid digestible Cr is given.
These CRMs are intended for use in quality assurance of measurements of elements in
polymers and related matrices. keywords: Industrial material, Polymers, Trace elements, Heavy metals
