描述

一般說明

Each unit of SRM 3131a includes five 10 mL sealed borosilicate glass ampoules containing an acidified aqueous solution. This solution is prepared gravimetrically to have a known mass fraction of magnesium. It contains nitric acid at a volume fraction of approximately 10%, which corresponds to an amount-of-substance concentration (molarity) of about 1.6 mol/L. For more information, please refer to the COA and SDS.
