Description
Tungsten Standard Solution is a metallo-organic standard containing 5000 mg/kg W in 20 cSt hydrocarbon oil, presented as a ROTI®Star preparation for AAS and ICP. The 50 ml pack weighs 0,100 kg and is characterised by a density of 0,862 g/cm³, a flash point of 115 °C and a boiling point greater than 218 °C. These data describe the hydrocarbon-oil matrix in which tungsten is dissolved at the stated mass fraction. From manufacturer Carl ROTH, the solution belongs to the analytical chemicals used as metallo-organic standards when atomic absorption spectrometry or inductively coupled plasma methods require an oil-soluble tungsten reference. The 20 cSt hydrocarbon oil vehicle carries the tungsten content, and the density of 0,862 g/cm³ allows laboratories to relate weighed aliquots to volume when taking portions from the 50 ml unit. Flash point and boiling point values (115 °C and >218 °C) inform handling of the organic matrix. With tungsten fixed at 5000 mg/kg W, this ROTI®Star standard is used for AAS and ICP determination of W in organic matrices.

Questions about Tungsten Standard Solution ROTI®Star, 5000 mg/kg W in 20 cSt Hydrocarbon Oil
What is this article?
Tungsten Standard Solution ROTI®Star, 5000 mg/kg W in 20 cSt Hydrocarbon Oil 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?
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.
