Supplier:  Sigma Aldrich Fine Chemicals Biosciences NIST3126A

This Standard Reference Material (SRM) is intended for use as a primary calibration standard for the quantitative determination of iron. A unit of SRM 3126a consists of five 10 mL sealed borosilicate glass ampoules of an acidified aqueous SOLUTIONon prepared gravimetrically to contain a known mass fraction of iron. The SOLUTIONon contains nitric acid at a volume fraction of approximately 10 % equivalent to an amount-of-substance concentration (molarity) of approximately 1.6 mol/L.
