This Standard Reference Material (SRM) 2777 is a naturally weathered Gulf of Mexico crude oil that is diluted in toluene. NIST-2777 is intended for use in evaluating analytical methods for the determination of polycyclic aromatic hydrocarbons (PAHs) in weathered crude oil matrices. All the constituents for which certified and reference values are provided are naturally present in the weathered oil. A unit of NIST-2777 consists of five ampoules, each containing approximately 1,2 mL of crude oil solution. /// Sample value(s) - please ask for current certificate.
