General description
This Standard Reference Material (SRM) is intended for use as a primary calibration standard for the quantitative determination of the arsenic species arsenous acid (AsIII). This SRM can be used for quality assurance when assigning values to in-house control materials. A unit of SRM 3037 consists of two 10 mL sealed borosilicate glass amber ampoules of an acidified aqueous solution prepared gravimetrically to contain a known mass fraction of arsenous acid. The solution contains hydrochloric acid at a volume fraction of approximately 1 %, which is equivalent to a concentration (molarity) of approximately 0.12 mol/L. Due to digestion of the starting material, arsenic trioxide, with sodium hydroxide, sodium is present in the ampoules at approximately 1000 mg/kg.SRM 3037_cert SRM 3037 _SDS
