Description
ICP Multi-Element Standard Solution CR-21 is a ROTI®Star multi-element calibration standard containing 19 elements in 5 % nitric acid for atomic spectroscopy workflows. The solution has a density of approximately 1 g/cm³ and a boiling point of 100 °C, and is classified under UN number 2031. Laboratories performing multi-element determinations benefit from a ready-to-use CR-21 composition that fits established ICP multi-element standard protocols. This preparation from manufacturer Carl ROTH is positioned for spectroscopy and spectrometry applications within atomic spectroscopy (AAS, ICP-OES, ICP-MS) and multi-element standards for ICP-OES. The nitric acid matrix helps maintain elemental stability for calibration series, method verification and instrument performance checks.
This article is part of ICP, AAS & ion standards, in Analytical standards & reference materials.

Questions about Multi-Element ICP Standard Solution CR-21, 100 ml, 19 elements in 5 % HNO3
What is this article?
Multi-Element ICP Standard Solution CR-21, 100 ml, 19 elements in 5 % HNO3 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?
The category is Analytical standards & reference materials. The sub-category is ICP, AAS & ion standards. The catalogue is Lab chemicals.
