Description
Tungsten ICP Standard Solution ROTI®Star is a single-element calibration standard containing 1000 mg/l tungsten (W) in a matrix of 1 %. HNO3 plus 2 %. HF. It is intended for trace elemental analysis by ICP-OES, ICP-MS, AAS and related techniques used in water analysis and laboratory quality control. The solution supports preparation of calibration curves and instrument performance checks for reliable quantification of tungsten in aqueous samples. This ROTI®Star standard from manufacturer Carl ROTH fits routine environmental monitoring, industrial process control and research workflows that require a defined tungsten reference. The acid matrix is classified under UN number 2922, reflecting the corrosive character of the nitric and hydrofluoric acid blend.
This article is part of ICP, AAS & ion standards, in Analytical standards & reference materials.

Questions about Tungsten ICP Standard Solution, ROTI®Star, 30 ml, HDPE
What is this article?
Tungsten ICP Standard Solution, ROTI®Star, 30 ml, HDPE 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.
Shelves beside this one are Chromatography standards (GC, HPLC, pesticides), Reference substances & reagents (other), Volumetric standard solutions (titration), Reagents for analysis (Ph. Eur., ASTM, DIN), Spectroscopy & physical property standards and Indicators & indicator solutions.
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.
