Beschreibung
Wolfraam ICP-standaardoplossing, ROTI®Star, 10000 mg/l W, dichtheid (D) 1 g/cm³
(Inductively Coupled Plasma – Optical Emission Spectrometry) De oplossingen en mengsels zijn gemaakt van materialen met de hoogste zuiverheid en voldoen daarom aan de vereisten voor instrumentele analyse door AAS en ICP. Alle oplossingen zijn gecertificeerd en herleidbaar naar NIST-standaardreferentieoplossingen (uitgezonderd: iridium, osmium en ruthenium). De oplossingen worden geproduceerd volgens ISO 17034 in een geaccrediteerde omgeving. De oplossingen worden getest in een laboratorium dat geaccrediteerd is volgens ISO/IEC 17025 en worden geleverd met een gedetailleerd, batchspecifiek analysecertificaat. Elke standaardoplossing is gemaakt van uitgangsmaterialen van hoge zuiverheid (meestal ≥99,999 %) en het gehalte wordt gravimetrisch en door middel van ICP bepaald. Voor de productie van de oplossingen worden hoogwaardige zuren (gezuiverd door sub-kokingdestillatie) en water gebruikt. Dit geeft u eersteklas referentiematerialen van de hoogste zuiverheid en kwaliteit.

Questions about Wolfraam ICP standaardoplossing
What is this article?
Wolfraam ICP standaardoplossing 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 Labor- und Industriechemikalien.
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 Labor- und Industriechemikalien.
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.
