Description
This Standard Reference Material (SRM) is intended for use in evaluating analytical methods for the determination of selected polycyclic aromatic hydrocarbons (PAHs) and nitro-substituted PAHs in diesel particulate extracts and similar matrices. In addition to certified, reference, and information values for selected PAHs and nitro-subsituted PAHs, reference values are provided for extract residue mass, and mutagenic activity. All of the chemical constituents for which certified and reference values are provided in NIST-1975 were naturally present in the particulate material before extraction. A unit of NIST-1975 consists of four ampoules, each containing approximately 1.2 mL of a dichloromethane extract of diesel particulate matter collected from an industrial dieselpowered forklift. Certified values /// Sample value(s) - please ask for current certificate.
