Description
PCB Solution ROTI®Star is a ready-to-use multi-congener reference mixture containing eight polychlorinated biphenyls at 10 µg/ml in cyclohexane. The blend comprises PCB 28, PCB 31, PCB 52, PCB 101, PCB 118, PCB 138, PCB 153 and PCB 180, supporting calibration and quality control in environmental residue work. Supplied as 1 ml in a glass ampoule, the solution shows a density of 0,78 g/cm³, a flash point of −20 °C and a boiling range of 80 to 81 °C. This formulation from manufacturer Carl ROTH is intended for gas-chromatographic determination of PCBs in environmental analysis and related chromatography workflows. The cyclohexane matrix offers convenient handling for standard preparation, spike recovery checks and instrument performance verification. Laboratories engaged in monitoring persistent organic pollutants can integrate the mixture into routine GC methods without additional weighing of individual congeners. Clear labelling of the eight target PCBs aids method documentation and traceability across analytical batches.
This article is part of HPLC & LC-MS grade solvents, in Solvents. See also Analytical grade solvents (p.a.).

Questions about PCB Solution ROTI®Star, 8 PCBs 10 µg/ml in cyclohexane, 1 ml, glass ampoule
What is this article?
PCB Solution ROTI®Star, 8 PCBs 10 µg/ml in cyclohexane, 1 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.
