Description
Anion multi-element standard (IC) ROTI®Star provides a three-anion reference solution for ion chromatography, formulated with chloride (Cl⁻), nitrate (NO3⁻) and sulfate (SO4²⁻) in water. Concentrations are expressed in mg/l, making the standard suitable for calibration, verification and routine multi-anion IC analysis in environmental and laboratory chromatography settings. The aqueous matrix shows a density of about 1 g/cm³ and a boiling point of 100 °C. This ROTI®Star multi-element preparation from manufacturer Carl ROTH helps laboratories maintain consistent anion references for Cl⁻, NO3⁻ and SO4²⁻ without preparing mixed standards from individual stock solutions. It fits applications in environmental analysis and ion chromatography where a defined three-anion water-based standard is required for method performance and day-to-day quantitative work.
This article is part of ICP, AAS & ion standards, in Analytical standards & reference materials.

Questions about Anion Multi-Element IC Standard Solution, 100 ml, 3 anions (Cl-, NO3-
What is this article?
Anion Multi-Element IC Standard Solution, 100 ml, 3 anions (Cl-, NO3- 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.
