Description
Anion multi-element standard (IC) ROTI®Star is an aqueous multi-anion calibration standard for ion chromatography containing seven anions. Concentrations are fluoride 100 mg/l, chloride 1000 mg/l, bromide 100 mg/l, nitrite 100 mg/l, nitrate 1000 mg/l, phosphate 100 mg/l and sulfate 1000 mg/l in water. Density is 1,005 g/cm³ and the boiling point is 100 °C. The standard is This IC multi-element standard from manufacturer Carl ROTH supports calibration and control measurements where simultaneous reference values for F⁻, Cl⁻, Br⁻, NO2⁻, NO3⁻, PO4³⁻ and SO4²⁻ are required. The defined mg/l levels in an aqueous matrix simplify preparation of working standards for ion-chromatography systems. Laboratories engaged in water, environmental and anion profiling can use the seven-anion mixture within routine IC calibration sequences. ROTI®Star 7 anions provides a ready multi-element reference format aligned with common anion determination workflows.
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?

What should I check before I order?
The technical information on this page is the manufacturer's sheet. Read that, not a rewritten specification.
When this page shows a safety data sheet, use that manufacturer file. Hazard text does not belong in the sales description. For a pack size, a grade or a certificate that is not on the page, send a quote request or contact the team.
