Beschrijving
De ICP-MS multi-element standaardoplossing CR-58 ROTI®Star is een gebruiksklare kalibratiestandaard die vierentwintig elementen in 5 % HNO3 bevat voor inductief gekoppelde plasma-massaspectrometrie. Het mengsel bevat As, Ba, Bi, Cd, Co, Cr, Cs, Cu, Fe, Ga, K, Mn, Na, Ni, P, Pb, Rb, Se, Sr, Th, Tl, U, V en Zn in gedefinieerde concentraties, waarbij kalium en natrium aanwezig zijn in een concentratie van 1000, fosfor 100 en de overige analyten 10. De dichtheid is ongeveer 1 g/cm³ en het kookpunt ligt boven 83 °C, wat bijdraagt aan een stabiele hantering in het laboratorium. Deze ROTI®Star multi-element standaard van fabrikant Carl ROTH wordt geleverd in een verpakking van 100 ml en is geschikt voor instrumentkalibratie, methodevalidatie en continue kwaliteitscontrole in ICP-MS-werkstromen. Laboratoria die zich bezighouden met milieumonitoring, materiaalonderzoek en wetenschappelijk onderzoek kunnen efficiënt gemengde kalibratiereeksen bereiden en een consistente multi-elementrespons handhaven voor hoofd-, neven- en sporencomponenten. De samenstelling van de CR-58 vermindert de afhankelijkheid van grote sets enkelvoudige elementstandaarden en past bij waterige salpeterzuur-monsterwegen die typisch zijn voor routinematige ICP-MS sporenelementanalyse.
Dit artikel hoort bij ICP, AAS & ionenstandaarden, in Analytische standaarden & referentiematerialen.

Questions about ICP-MS Multi-Element Standaardoplossing
What is this article?
ICP-MS Multi-Element 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 Chemicaliën.
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 Chemicaliën.
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.
