Coal fly ash

Application
Coal fly ash standard Reference Material (SRM) is intended for use in assessing the analytical methods used to classify coal fly ash and to determine constituent elements in coal fly ash or similar matrix.
Features and Benefits
NIST Certified Mass Fraction values for constituent elements are traceable to NIST’s realization of the SI unit of the kilogram and expressed as a percentage.
Information values for constituent elements are expressed as mass fraction.
Expiration details and instructions for use, storage, and handling are provided on the NIST certificate.
General description
SRM 2691 contains three hermetically sealed glass vials, each containing 10 g of fly ash pulverized to a particle size of less than 150 µm and thoroughly blended to ensure a high degree of homogeneity. For more information, please refer to the SDS and COA.
