Abstract | CLED-1 is a high purity isotopic lead Certified Reference Material (CRM). A unit of CLED-1 consists of 1 mL lead solution at 100 mg/kg in 2 % nitric acid that was prepared by mixing separated lead isotope materials to obtain approximately 2:3 ratio of lead-206 and lead-208. This material is intended as an isotopic standard of lead. Certified values for the isotopic composition and the atomic weight of lead have been established for this CRM. |
