Calcium (Ca) standard solution

Description

• General description: This Standard Reference Material (SRM) is intended for use as a primary calibration standard for the quantitative determination of calcium. A unit of SRM 3109a consists of five 10 mL sealed borosilicate glass ampoules of an acidified aqueous solution prepared gravimetrically to contain a known mass fraction of calcium. The solution contains nitric acid at a volume fraction of approximately 10 %, equivalent to an amount-of-substance concentration (molarity) of approximately 1.6 mol/L.
