    dct:description "This Standard Reference Material (SRM) is intended for use as a primary calibration standard for the quantitative determination of mercury.  A unit of SRM 3133 consists of five 10 mL sealed borosilicate glass ampoules of an acidified aqueous solution prepared gravimetrically to contain a known mass fraction of mercury.  The solution contains nitric acid at an approximate mass fraction of 10 %. This data is public in the Certificate of Analysis for this material." ;
