Description

This Standard Reference Material (SRM®) is intended primarily for validating analytical methods and measurements for the determination of toxic elements and anions in human urine. A unit of SRM 3668 consists of five vials of each of two levels. Each vial contains nominally 1.5 mL of urine. NIST-3668 is shipped on dry ice, and it should be stored at -70 °C until use. Certified values /// 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.
