Description
Cation Multi-element standard (IC) ROTI®Star is an aqueous multi-cation reference solution prepared for ion chromatography. The 100 ml pack contains five cations at defined concentrations in water: NH4⁺ at 3,88 mg/l, Ca²⁺ at 10 mg/l, K⁺ at 5 mg/l, Mg²⁺ at 5 mg/l and Na⁺ at 20 mg/l. Density is approximately 1 g/cm³ and the boiling point is about 100 °C, consistent with a water-based matrix that handles like routine aqueous standards. Environmental analysis, water testing and IC method calibration benefit from a single multi-element solution that delivers ammonium, calcium, potassium, magnesium and sodium together. This ROTI®Star preparation from manufacturer Carl ROTH is aimed at laboratories that require stable multi-cation references for calibration curves, system suitability and quality control. The ready-to-use 100 ml format reduces preparation steps and supports reproducible ion-chromatographic workflows across environmental and general analytical applications where these five cations are monitored.
This article is part of ICP, AAS & ion standards, in Analytical standards & reference materials.

Questions about IC standards, 500 ml, 5 cations (NH4+, Ca2+, K+, Mg2+, Na+) in H2O
What is this article?
IC standards, 500 ml, 5 cations (NH4+, Ca2+, K+, Mg2+, Na+) 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.

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.
