NIST Special Publication 260-215 . Standard Reference Material (SRM) 1936 Great Lakes Sediment is intended for 1) use in validating calibration and validation materials for sediment analysis methods value and 2) assigning in-house produced control materials analyzed using those methods. A unit of SRM

Purpose: This Standard Reference Material (SRM) is intended for the evaluation of methods for the determination of proximates, sugars, elements, amino acids, and fatty acids in mixed diets and food matrices and for quality assurance when assigning values to inhouse control materials. - 1548b is a blended freezeSRM -dried homogenate of foods
