Abstract
WOLF-1 is an isotopic Certified Reference Material (CRM) of natural tungsten. A unit of WOLF-1 consists of approximately 1 mL aliquot of tungsten solution at 1000 mg kg–1 in H2O. This material is intended for the calibration of instruments and evaluation of analysis methods for the determination of isotope ratios of tungsten. Certified values for isotope amount ratios, isotope abundances and atomic weight of tungsten have been established for this isotopic reference material.
