This Standard Reference Material (SRM) is intended primarily for use in validation of chemical and instrumental methods of analysis used to determine elements in hard rock mine waste and materials of a similar matrix. It can be used to validate value assignment of in-house reference materials. NIST-2780a is composed of material collected from waste piles of abandoned mine sites in the mountains of central Colorado. A unit of NIST-2780a consists of approximately 50 g of material of which 90 % passes a 150 µm (No. 100) sieve. /// Sample value(s) - please ask for current certificate.

Muster-CoA des Referenzmaterials: für die aktuelle Charge kontaktieren Sie unseren Kundendienst unter info@labmix24.com
NIST bietet über 1300 Standardreferenzmaterialien sowie Artikel und Praxisleitfäden, die die Entwicklung, Analyse und Verwendung von SRMs beschreiben.
NIST-Standardreferenzmaterialien werden von analytischen Laboratorien in Industrie, Wissenschaft und Regierung verwendet, um Handel und Gewerbe zu erleichtern und Forschung und Entwicklung voranzutreiben. Die SRMs werden vom Ingenieurlabor, dem Materialmesslabor und dem physikalischen Messlabor des NIST hergestellt. Sie stehen für chemische Zusammensetzung, physikalische Eigenschaften und technische Materialien zur Verfügung.
