General description

This Standard Reference Material (SRM) is intended for use as a primary calibration standard for the quantitative determination of platinum. A unit of SRM 3140 consists of five 10 mL sealed borosilicate glass ampoules of anacidified aqueous solution prepared gravimetrically to contain a known mass fraction of platinum. The solution contains hydrochloric acid at a volume fraction of approximately 10 %, which is equivalent to a concentration(molarity) of approximately 1.2 mol/L. For more information, please refer to the COA and SDS.SRM 3140_cert SRM 3140 _SDS
