Description

This Standard Reference Material( (SRM®) is a mixture of three polycyclic aromatic hydrocarbons (PAHs) in acetonitrile: benzo[a]pyrene (BaP), 1,2:3,4:5,6:7,8-tetrabenzonaphthalene (TBN, dibenzo[g,p]chrysene), and phenanthro[3,4-c]phenanthrene (PhPh). NIST-869b is useful for characterising liquid chromatographic (LC) column selectivity for separation of PAHs. Depending on the elution order of the three components, column selectivity can be predicted for complex PAH mixtures (particularly isomeric PAHs). Even though the primary use of this mixture in the past has been to characterise columns for PAH separations, applications to the assessment of column selectivity for other classes of compounds such as carotene isomers has also been demonstrated. A unit of NIST-869b consists of 5 ampoules, each containing 1.1 mL of the PAH mixture. /// Sample value(s) - please ask for current certificate.

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.
