Description
La solution étalon ICP de tungstène ROTI®Star est un étalon de calibration mono-élément contenant 1000 mg/l de tungstène (W) dans une matrice de 1 % HNO3 et 2 % HF. Elle est destinée à l'analyse élémentaire par traces par ICP-OES, ICP-MS, AAS et techniques apparentées utilisées dans l'analyse de l'eau et le contrôle qualité en laboratoire. La solution permet d'établir des courbes de calibration et de vérifier les performances des instruments pour une quantification fiable du tungstène dans les échantillons aqueux. Cet étalon ROTI®Star du fabricant Carl ROTH est adapté au suivi environnemental de routine, au contrôle des processus industriels et aux flux de travail de recherche nécessitant une référence définie de tungstène. La matrice acide est classée sous le numéro ONU 2922, reflétant le caractère corrosif du mélange d'acide nitrique et d'acide fluorhydrique.
Cet article fait partie des étalons ICP, AAS et d'ions, dans les étalons analytiques et matériaux de référence.

Questions about Solution étalon ICP de tungstène, ROTI®Star, 30 ml, PEHD
What is this article?
Solution étalon ICP de tungstène, ROTI®Star, 30 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.
Shelves beside this one are Chromatography standards (GC, HPLC, pesticides), Reference substances & reagents (other), Volumetric standard solutions (titration), Reagents for analysis (Ph. Eur., ASTM, DIN), Spectroscopy & physical property standards and Indicators & indicator solutions.
What should I check before I order?
The technical information on this page is the manufacturer's sheet. Read that, not a rewritten specification.
When this page shows a safety data sheet, use that manufacturer file. Hazard text does not belong in the sales description. For a pack size, a grade or a certificate that is not on the page, send a quote request or contact the team.
