Description
This Standard Reference Material (SRM®) is intended for use in establishing a reference scale for fluorescence intensity based upon Molecules of Equivalent Soluble Fluorophore (MESF) units. This SRM is certified for the concentration of fluorescein with a certified purity in a borate buffer solution. The MESF scale is established for a particular set of experimental conditions by measuring the fluorescence intensity of known amounts of this SRM under a specific set of conditions (see ?Instructions for Use?). A unit of NIST-1932 consists of three flamed sealed amber glass ampoules, each containing approximately 2.0 mL of fluorescein in an aqueous borate buffer. Reference Values for Molar Absorption Coefficient, and Fluorescein Purity Determinations. /// 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.
