Description
PCB Solution ROTI®Star is a multi-congener calibration mixture providing eight polychlorinated biphenyls at 1 µg/ml in n-hexane. Included congeners are PCB 28, PCB 52, PCB 101, PCB 118, PCB 138, PCB 153, PCB 180 and PCB 194, suited to environmental analysis and gas-chromatographic quantification. The product is packed as 5 ml in a glass ampoule and exhibits a density of 0,66 g/cm³, a flash point of −22 °C and a boiling range of 68 to 69 °C. Available from manufacturer Carl ROTH, this lower-concentration standard supports working-level calibrations, method validation and ongoing quality control without intermediate dilution steps in many GC protocols. The n-hexane matrix is widely compatible with common sample-preparation schemes used for soil, water and biota extracts. Clear identification of the eight target PCBs simplifies documentation for accredited laboratories monitoring persistent organic pollutants. The ampoule format helps preserve solution integrity until the moment of use in chromatography workflows.

Questions about PCB Solution ROTI®Star, 8 PCBs 1 µg/ml in n-hexane, 5 ml, glass ampoule
What is this article?
PCB Solution ROTI®Star, 8 PCBs 1 µg/ml in n-hexane, 5 ml, glass ampoule 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 Lab chemicals.
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 Lab chemicals.
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.
