This Standard Reference Material (SRM®) is intended primarily for use in validating methods for determining elements, arsenic species, vitamin K1, and proximates in kelp and similar matrices. This SRM can also be used for quality assurance when assigning values to in-house control materials. A unit of NIST-3232 consists of three heat-sealed, aluminized pouches, each containing approximately 5 g of material. /// Sample value(s) - please ask for current certificate.

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.
