Description
Anion Multi-element standard (IC) is an aqueous calibration solution containing seven anions for ion chromatography. The ROTI®Star preparation provides fluoride at 15 mg/l, chloride at 1000 mg/l, bromide at 10 mg/l, nitrate at 500 mg/l, nitrite at 5 mg/l, phosphate at 100 mg/l, and sulfate at 1000 mg/l in water, enabling multi-anion calibration from a single standard. Physical properties include a density of about 1 g/cm³ and a boiling point near 100 °C. The aqueous matrix supports direct use or dilution according to method requirements for conductivity or suppressed IC detection. This multi-anion IC standard streamlines routine calibration and quality-control checks by combining F⁻, Cl⁻, Br⁻, NO2⁻, NO3⁻, PO4³⁻, and SO4²⁻ in defined concentrations, reducing the need to blend separate single-anion stocks for everyday chromatographic work.
This article is part of ICP, AAS & ion standards, in Analytical standards & reference materials.

Questions about IC standards, 100 ml, 7 anions (F-, Cl-, Br-, NO2-, NO3-, PO43-, SO42-) in H2O
What is this article?
IC standards, 100 ml, 7 anions (F-, Cl-, Br-, NO2-, NO3-, PO43-, SO42-) 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.
Which category should I open next?
