Description

This Standard Reference Material (SRM®) is intended primarily for use in evaluating methods used in the determination of trace elements in fresh water. NIST-1643f consists of approximately 250 mL of acidified water in a polyethylene bottle, which is sealed in an aluminized plastic bag to maintain stability. NIST-1643f simulates the elemental composition of fresh water. The solution contains nitric acid at a volume fraction of approximately 2 %, equivalent to an amount of substance concentration (molarity) of approximately 0.32 mol/L.

NIST | National Institute of Standards and Technology

NIST provides over 1300 Standard Reference Materials® as well as articles and practice guides describing the development, analysis and use of SRMs.

NIST Standard Reference Materials are used by analytical laboratories in industry, academia and government in order to facilitate commerce and trade and to advance research and development. The SRMs are produced by the engineering laboratory, the material measurement laboratory, and the physical measurement laboratory at NIST. They are available for chemical composition, physical properties, and engineering materials.
