Beschrijving
VOC/aromatenmengsel 1 is een ROTI®Star-kalibratiestandaard met meerdere componenten die twaalf vluchtige organische en aromatische verbindingen bevat, elk bij 1000 mg/l in methanol. Het mengsel omvat dichloromethane, chloroform, 1.1,1-trichloroethane, tetrachloromethane, trichloroethene, tetrachloroethene, benzene, toluene, ethylbenzene, m-xylene, p-xylene en o-xylene, ter ondersteuning van kalibratie met meerdere analyten en kwaliteitscontrolewerk in gaschromatografische VOC-methoden. Fysische gegevens omvatten een dichtheid van 0.79 g/cm³, een vlampunt van 10 °C en een kookpunt van 65 °C. De standaard wordt geleverd als 1 ml in een glazen ampul van fabrikant Carl ROTH en biedt een handig formaat voor eenmalig gebruik dat verdamping en kruiscontaminatie tussen runs beperkt. Laboratoria die milieu-, arbeidshygiëne- of oplosmiddelresiduanalyses uitvoeren, kunnen dit mengsel gebruiken om responsfactoren vast te stellen, retentietijdvensters te controleren en de detectorprestaties over gechloreerde en aromatische doellijsten in één injectiesequentie te verifiëren.

Questions about VOC/aromatenmengsel 1, ROTI®Star 12 componenten in methanol, 1 ml, glazen ampul
What is this article?
VOC/aromatenmengsel 1, ROTI®Star 12 componenten in methanol, 1 ml, glazen ampul is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Oplosmiddelen van HPLC- & LC-MS-kwaliteit, inside Oplosmiddelen, in Chemicaliën.
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.

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.
