Beschreibung
WHO/ISS PCB-oplossing ROTI®Star is een uitgebreid referentiemengsel van polychloorbifenylen met 32 PCB-congeneren in een concentratie van 10 µg/ml in isooctaan, ontworpen voor milieu-analyse en gaschromatografie. Het omvattende panel beslaat PCB 18, 28, 31, 44, 52, 77, 81, 95, 99, 101, 105, 110, 114, 118, 123, 126, 128, 138, 146, 149, 151, 153, 156, 157, 167 , 169, 170, 177, 180, 183, 187 en 189, waarbij WHO- en ISS-relevante congeneren in één oplossing worden gecombineerd. De fysische eigenschappen omvatten een dichtheid van 0,69 g/cm³, een vlampunt van −12 °C en een kookpunt van 99,2 °C. Het preparaat wordt geleverd in een eenheid van 1 ml en is geschikt voor kalibratie, methodevalidatie en PCB-bepaling van meerdere residuen middels GC. Laboratoria die brede milieu-PCB-screening uitvoeren, beschikken hiermee over een kant-en-klare isooctaanstandaard die het hanteren van talloze individuele congenerenvoorraden vermindert. Dit ROTI®Star-product van fabrikant Carl ROTH ondersteunt chromatografische workflows die een brede WHO/ISS PCB-dekking in één gedefinieerd concentratieniveau vereisen voor een efficiënte analytische opzet.
Dit artikel hoort bij ICP-, AAS- en ionenstandaarden, in Analytische standaarden & referentiematerialen.

Questions about WHO/ISS PCB-oplossing ROTI®Star, 32 PCB's 10 µg/ml in isooctaan, 1 ml
What is this article?
WHO/ISS PCB-oplossing ROTI®Star, 32 PCB's 10 µg/ml in isooctaan, 1 ml 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.
