Description
Cation Multi-element standard (IC) ROTI®Star is a ready-to-use multi-cation calibration solution for ion chromatography, offering six common cations at 100 mg/l in aqueous matrix. The preparation contains ammonium (NH4⁺), calcium (Ca²⁺), potassium (K⁺), lithium (Li⁺), magnesium (Mg²⁺) and sodium (Na⁺) dissolved in H2O, supporting simultaneous multi-element calibration and method checks in a single standard. Physical data include a density of approximately 1 g/cm³ and a boiling point of 100 °C, consistent with a water-based IC reference. Packed as 100 ml in an HDPE bottle, the standard suits routine laboratory handling and storage on the bench or in calibration sets. This ROTI®Star formulation from manufacturer Carl ROTH is intended for environmental analysis, water testing and other chromatographic workflows where reliable cation response factors are required. Laboratories can use the balanced six-cation mix to streamline calibration sequences, system suitability tests and quality-control runs without preparing individual single-element standards for each analyte.
This article is part of ICP, AAS & ion standards, in Analytical standards & reference materials.

Questions about Cation Multi-element standard (IC), ROTI®Star 6 cations, 100 mg/l, 100 ml, HDPE
What is this article?
Cation Multi-element standard (IC), ROTI®Star 6 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.
