Aplicação

Potassium (K) standard solution SRM is intended for primary use as a calibration standard for quantitative determination of potassium.

Características e benefícios

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

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

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