Published by National Institute of Standards and Technology | National Institute of Standards and Technology | Metadata Last Checked: August 02, 2025 | Last Modified: 2016-09-14 00:00:00
This Standard Reference Material (SRM) is intended for use as a primary calibration standard for the quantitative determination of antimony. A unit of SRM 3102a consists of 50 mL of an acidified aqueous solution prepared gravimetrically to contain a known mass fraction of antimony in a high-density polyethylene bottle sealed in an aluminized bag. The solution contains nitric acid at a volume fraction of approximately 10 % and hydrofluoric acid at a volume fraction of approximately 2 %, equivalent to amount of substance concentrations (molarities) of approximately 1.6 mol/L and 0.6 mol/L respectively. This data is public in the Certificate of Analysis for this material.
