Descrizione

Descrizione generale

Each unit of SRM 3134 contains five sealed borosilicate glass ampoules, each containing 10 mL of an acidified aqueous solution, gravimetrically prepared to have a known mass fraction of molybdenum.The solution includes approximately 10% volume fraction of hydrochloric acid, corresponding to an approximate molarity of 1.2 mol/L.

Applicazioni

The SRM is intended as a primary calibration standard for the quantitative molybdenum determination.

Caratteristiche e vantaggi

• The certified value of the SRM was determined by calculating the mass fraction values of mercury, which is obtained through two methods:

1. Gravimetric preparation using high-purity molybdenum metal assayed by NIST
2. Isotope-dilution cold-vaporinductively coupled plasma – mass spectrometry (ID-ICP-MS).

• The certified value is metrologically traceable to the SI unit of mass fraction, expressed as micrograms per gram.
• The NIST certificate is provided with period of validity, storage, handling, use, and maintenance instructions.
