SRM 3131a Magnesium (Mg) Standard Solution Lot 140110

This Standard Reference Material (SRM) is intended for use as a primary calibration standard for the quantitative determination of magnesium. A unit of SRM 3131a consists of five 10 mL sealed borosilicate glass ampoules of an acidified aqueous solution prepared gravimetrically to contain a known mass fraction of magnesium. 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. This data is public in the Certificate of Analysis for this material.
