Beschreibung
PCB-oplossing ROTI®Star is een gebruiksklaar referentiemengsel met meerdere congeneren, bevattende acht polychloorbifenylen met een concentratie van 10 µg/ml in cyclohexaan. Het mengsel bestaat uit PCB 28, PCB 31, PCB 52, PCB 101, PCB 118, PCB 138, PCB 153 en PCB 180, ter ondersteuning van kalibratie en kwaliteitscontrole bij residu-onderzoek in het milieu. Geleverd als 1 ml in een glazen ampul, vertoont de oplossing een dichtheid van 0,78 g/cm³, een vlampunt van -20 °C en een kooktraject van 80 tot 81 °C. Deze formulering van fabrikant Carl ROTH is bedoeld voor gaschromatografische bepaling van PCB's bij milieuanalyses en gerelateerde chromatografische werkstromen. De cyclohexaan-matrix biedt gebruiksgemak voor standaardpreparatie, controle op terugwinning van spikes en verificatie van instrumentprestaties. Laboratoria die zich bezighouden met het monitoren van persistente organische verontreinigende stoffen kunnen het mengsel integreren in routinematige GC-methoden zonder dat individuele congeneren apart hoeven te worden afgewogen. De duidelijke etikettering van de acht doel-PCB's helpt bij de methodedocumentatie en traceerbaarheid over analytische batches heen.
Dit artikel hoort bij HPLC- en LC-MS-solventen, in Solventen. Zie ook Analytische solventen (p.a.).

Questions about PCB-oplossing ROTI®Star, 8 PCB's 10 µg/ml in cyclohexaan, 1 ml, glazen ampul
What is this article?
PCB-oplossing ROTI®Star, 8 PCB's 10 µg/ml in cyclohexaan, 1 ml, glazen ampul is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in HPLC & LC-MS grade solvents, inside Solvents, in Labor- und Industriechemikalien.
HPLC grade limits the absorbance and the residue that would appear as peaks or baseline drift. LC-MS grade goes further on metal ions and on particles that would suppress a mass spectrum. A solvent that is only analytical grade is a false economy on an LC-MS system.
A solvent dissolves. The grade says which impurities are low enough for the method. Analytical grade is the ordinary pure solvent. HPLC and LC-MS grades limit the absorbance and the ions that would become peaks or background. A dry solvent has had water removed. A deuterated solvent is for NMR, where the hydrogen signal would otherwise drown the sample. Technical grade is for cleaning and for synthesis that does not need a chromatogram. Identity is on PubChem. Names follow IUPAC. Hazards follow ECHA, the CLP Regulation and REACH.
Which category should I open next?
The category is Solvents. The sub-category is HPLC & LC-MS grade solvents. The catalogue is Labor- und Industriechemikalien.
Shelves beside this one are Analytical grade solvents (p.a.), Dry & deuterated solvents (NMR, synthesis), Technical & synthesis grade solvents and Green & alternative solvents.
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.
