Hafnium (Hf) standard solution

NA.24

This Standard Reference Material (SRM) is intended for use as a primary calibration standard for the quantitative determination of hafnium. A unit of SRM 3122 consists of 50 mL of an acidified aqueous solution prepared gravimetrically to contain a known mass fraction of hafnium in a high-density polyethylene bottle sealed in an aluminized bag. The solution contains approximately 8 % nitric acid (volume fraction) and approximately 1 % hydrofluoric acid (volume fraction), equivalent to amount-of-substance concentrations (molarities) of 1.3 mol/L and 0.3 mol/L, respectively. For more information, please refer to the SDS and COA.
