This Standard Reference Material (SRM®) is intended primarily for use in the analysis of waste, soils, sediments, or other materials of a similar matrix. NIST-is a soil, heavily contaminated with chromite ore processing residue (COPR), that has been air-dried, sieved, radiation-sterilized, and blended to achieve a high degree of homogeneity. All constituents in NIST-2701 for which certified, reference, and information values are provided were naturally present in the material before processing. A unit of NIST-2701 consists of approximately 75 g of the dried, radiation-sterilized material in an amber screw-capped glass bottle.
