Description

General description

This Standard Reference Material (SRM) is intended for use as an analytical standard of known potassium (K) and chloride (Cl^?) content. This lot of potassium chloride (KCl) was prepared to ensure a material of high purity and homogeneity and has been assayed after drying at 500 °C. A unit of SRM 999c consists of a single glass bottle containing 30 g of the material.
