Description
Le standard multi-élément de cations (CI) ROTI®Star 4 cations est une solution d'étalonnage aqueuse pour chromatographie ionique contenant du sodium, du potassium, du magnésium et du calcium, chacun à 10 mg/l (Na⁺, K⁺, Mg²⁺, Ca²⁺ dans l'eau). Le mélange multi-cations facilite l'étalonnage, la vérification et les travaux courants de quantification par CI dans l'analyse environnementale et les méthodes d'échange cationique associées. Les analystes peuvent utiliser cette préparation à quatre cations pour établir des courbes d'étalonnage, vérifier la réponse de l'instrument et rationaliser le contrôle qualité lorsque plusieurs cations majeurs doivent être quantifiés simultanément. Le standard ROTI®Star 4 cations du fabricant Carl ROTH est destiné aux applications professionnelles de chromatographie ionique qui nécessitent une solution de cations multi-élément définie à 10 mg/l. La liste explicite de Na⁺, K⁺, Mg²⁺ et Ca²⁺ permet d'adapter le standard aux spécifications des méthodes pour les déterminations CI des cations dans l'eau, l'environnement et l'analyse générale.
Cet article fait partie de ICP, AAS et standards ioniques, dans Standards analytiques et matériaux de référence.

Questions about Étalon multi-éléments de cations (CI), ROTI®Star 4 cations, 10 mg/l, 100 ml, PEHD
What is this article?
Étalon multi-éléments de cations (CI), ROTI®Star 4 cations, 10 mg/l, 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.
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.
