Abstract
ZIRC-1 is an isotopic Certified Reference Material (CRM) of natural zirconium. A unit of ZIRC-1 consists of approx. 1 mL aliquot of zirconium solution at 1000 mg kg–1 in 2 % HNO3 and 0.1 % HF. This material is intended as an isotopic standard for the calibration of instruments and evaluation of analysis methods for the determination of isotope ratios of zirconium. Certified values for the isotopic composition and the atomic weight of zirconium have been established for this CRM.
