Description
Cation Multi-element standard (IC) ROTI®Star is a ready-to-use ion chromatography standard containing nine cations at 100 mg/l in 0,1 % nitric acid. The cation set comprises NH4⁺, Ba²⁺, Ca²⁺, K⁺, Li⁺, Mg²⁺, Mn²⁺, Na⁺ and Sr²⁺, supporting multi-cation calibration and control in IC workflows. The solution is supplied in a 100 ml HDPE pack with an approximate density of 1 g/cm³ and a boiling point near 100 °C. Produced by manufacturer Carl ROTH under the ROTI®Star line, it is aimed at environmental analysis, chromatography, and ion chromatography laboratories that require a defined multi-cation reference. Pack weight is about 0,123 kg. The dilute nitric acid matrix suits aqueous IC methods where acid-compatible cation standards are preferred. Analysts can apply the 100 mg/l level for calibration, system suitability, and ongoing quality checks across the listed alkali, alkaline-earth, and related cations. The 100 ml HDPE presentation supports convenient handling and storage during routine ion-chromatographic cation determinations.
This article is part of ICP, AAS & ion standards, in Analytical standards & reference materials.

Questions about Cation Multi-element standard (IC), ROTI®Star 9 cations, 100 mg/l, 100 ml, HDPE
What is this article?
Cation Multi-element standard (IC), ROTI®Star 9 cations, 100 mg/l, 100 ml, HDPE 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 Lab chemicals.
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?
