Lead-206 and lead-208 double spike isotopic standard

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.

NRC Canada’s certified reference materials (CRMs) are traceable to the International System of Units, and conform to the requirements of ISO/IEC 17025 and ISO 17034.For specific values, as well as additional information regarding stability and storage information, please view the Certificate of Analysis.With NRC Canada’s CRMs, you gain access to products backed by extensive research and expertise, fostering trust and consistency in your results. Elevate your laboratory’s accuracy and credibility with NRC Canada’s certified reference materials.
