Description
La solution étalon AAS de zinc est un matériau de référence prêt à l'emploi de la gamme ROTI®Star, contenant 1000 mg/l de zinc (Zn) pour l'étalonnage et le contrôle qualité en spectrométrie d'absorption atomique. La solution présente une densité d'environ 1 g/cm³ et un point d'ébullition d'environ 100 °C, caractéristiques des matrices aqueuses diluées utilisées dans les méthodes AAS, ICP et IC. Les laboratoires spécialisés dans la surveillance environnementale et l'analyse élémentaire s'appuient sur ces étalons pour établir des courbes d'étalonnage et vérifier les performances des instruments. Proposée par le fabricant Carl ROTH, la préparation est classée sous le numéro ONU 3264 et est destinée à un usage analytique professionnel. Un étiquetage clair de la concentration en zinc facilite la préparation traçable d'étalons de travail conformément aux protocoles de laboratoire. Cet étalon AAS ROTI®Star s'intègre aisément dans les méthodes existantes de dosage des métaux au sein des laboratoires de recherche, industriels et environnementaux.
Cet article fait partie de Étals ICP, AAS et ions, dans Étalons analytiques et matériaux de référence.

Questions about Solution étalon d'absorption atomique de zinc, ROTI®Star, 100 ml, PEHD
What is this article?
Solution étalon d'absorption atomique de zinc, ROTI®Star, 100 ml, PEHD is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in ICP, AAS & ion standards, inside Analytical standards & reference materials, in Produits chimiques.
An ICP, AAS or ion standard is a solution of a stated element or ion at a stated concentration, with an uncertainty. It is the calibration point of a spectrometer or an electrode. The matrix, often dilute acid, has to match the method. A standard past its expiry is not that concentration.
A reference material is the article against which another result is compared. Its value is stated, and the uncertainty of that value is part of the product. An ICP or ion standard is a solution of known concentration. A volumetric standard is for titration. A chromatography standard is the peak you match. The grade names, including pharmacopoeia and ASTM, say which impurities were limited. Identity is checked on PubChem. Names follow IUPAC. Medicinal grades follow the European Pharmacopoeia and USP.
Which category should I open next?
The category is Analytical standards & reference materials. The sub-category is ICP, AAS & ion standards. The catalogue is Produits chimiques.
