Description
ICP Multi-Element Standard Solution CR-90 is a ROTI®Star multi-element standard for ICP applications, supplying seven elements in 10 % HNO3. Defined concentrations are Al 120 mg/l, Ca 12 mg/l, Mg 1800 mg/l, Mn 20 mg/l, Nd 60 mg/l, Y 80 mg/l and Zn 10 mg/l, enabling calibration and control measurements in atomic spectroscopy laboratories that rely on ICP-OES or related techniques. Physical data include a density of about 1 g/cm³ and a boiling point above 83 °C, with transport classification UN number 3264. The standard is supplied in a 100 ml pack at 0,12 kg, matching common bench-scale consumption for multi-element ICP work. Prepared by manufacturer Carl ROTH under the ROTI®Star line, CR-90 supports structured multi-element programmes where aluminium, calcium, magnesium, manganese, neodymium, yttrium and zinc must be introduced together in a nitric acid matrix. It fits analytical chemical workflows for spectroscopy and spectrometry, particularly multi-element standards for ICP-OES, and can be used wherever a compact seven-element blend in 10 % HNO3 is specified by method protocols.
This article is part of ICP, AAS & ion standards, in Analytical standards & reference materials.

Questions about ICP Multi-Element Standard Sol. CR-90
What is this article?
ICP Multi-Element Standard Sol. CR-90 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?
