Each unit of the SRM contains five sealed borosilicate glass ampoules, each consisting of 10 mL of an acidified aqueous solution. This solution is prepared through gravimetric methods to ensure a precise mass fraction of vanadium.
The certified value is metrologically traceable to the derived SI unit for mass fraction, expressed as milligrams pergram.
The NIST certificate is provided with expiration certificate, storage, handling,use and maintenance instructions.
