This Standard Reference Material (SRM®) is a highly purified and homogeneous lot of crystalline ammonium dihydrogen phosphate (NH4H2PO4). It is intended primarily for use as a working standard in the calibration and standardization of procedures employed in the fertilizer industry for the determination of ammoniacal nitrogen and phosphorus. A unit of NIST-194a consists of one bottle containing 90 g of crystalline ammonium dihydrogen phosphate. /// 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.
