Description
Cation Multi-element standard (IC) ROTI®Star is an aqueous multi-cation reference solution for ion chromatography, It contains five cations at the following concentrations in water: NH4⁺ at 38,83 mg/l, Ca²⁺ at 75 mg/l, K⁺ at 50 mg/l, Mg²⁺ at 50 mg/l and Na⁺ at 100 mg/l. Density is approximately 1 g/cm³ and the boiling point is about 100 °C, matching a water-based standard matrix used in routine IC work. Higher concentration levels make this mix suitable for calibration ranges, dilution series and quality-control checks in environmental and water analysis. Laboratories performing multi-cation IC benefit from a single solution that combines ammonium, calcium, potassium, magnesium and sodium. This ROTI®Star standard from manufacturer Carl ROTH supports professional ion-chromatography workflows where reproducible multi-element references are required.
This article is part of ICP, AAS & ion standards, in Analytical standards & reference materials.

Questions about IC standards, 100 ml, 5 cations (NH4+, Ca2+, K+, Mg2+, Na+) in H2O
What is this article?
IC standards, 100 ml, 5 cations (NH4+, Ca2+, K+, Mg2+, Na+) in H2O 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.
