Description
Anion Multi-element standard (IC) is an aqueous multi-anion calibration solution formulated for ion-chromatography methods used in environmental and water analysis. The ROTI®Star preparation contains four anions at defined concentrations: chloride at 100 mg/l, nitrite-nitrogen at 100 mg/l, nitrate-nitrogen at 100 mg/l and phosphate-phosphorus at 10 mg/l, all in water. Density is approximately 1 g/cm³ and the boiling point is near 100 °C, reflecting the aqueous matrix. Laboratories engaged in chromatography-based anion profiling can use the multi-element composition to establish response factors for Cl⁻, N(NO2⁻), N(NO3⁻) and P(PO4³⁻) within a single working solution, reducing the need to blend individual stocks when these target levels match the method range. The product sits within environmental-analysis and ion-chromatography application areas and supports routine monitoring workflows that demand consistent multi-anion reference material.
This article is part of ICP, AAS & ion standards, in Analytical standards & reference materials.

Questions about Anion Multi-Element IC Standard Solution, 100 ml, 4 anions (Cl-, NO2- (N)
What is this article?
Anion Multi-Element IC Standard Solution, 100 ml, 4 anions (Cl-, NO2- (N) 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.
