Descrição

Descrição geral

Each unit of SRM 3139 contains five 10 mL sealed borosilicate glass ampoules containing an acidified aqueous solution, prepared gravimetrically to contain a known mass fraction of phosphorus. The solution consists of around 0.8% nitric acid at a volume fraction.

Aplicação

Phosphorus (P)standard solution SRM is intended for use as a calibration standard for accurately determining phosphorus quantitatively.

Características e benefícios

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

1. Gravimetric preparation
2. Inductively coupled plasma optical emission spectrometry (ICP-OES)

• The certified value is metrologically traceable to the SI unit of mass fraction, expressed in units of milligrams per gram.
• The NIST certificate is provided with expiration certificate, storage, handling, use,and maintenance instructions.
