Description
WHO/ISS PCB Solution ROTI®Star is an extended multi-congener polychlorinated biphenyl reference mixture with 32 PCBs at 10 µg/ml in isooctane, designed for environmental analysis and gas chromatography. The comprehensive panel covers 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 and 189, aligning WHO- and ISS-relevant congeners in a single solution. Physical characteristics include a density of 0,69 g/cm³, a flash point of −12 °C and a boiling point of 99,2 °C. Supplied as a 1 ml unit, the preparation is suited to calibration, method validation and multi-residue PCB determination by GC. Laboratories performing broad environmental PCB screening gain a ready-made isooctane standard that reduces handling of numerous individual congener stocks. This ROTI®Star product from manufacturer Carl ROTH supports chromatographic workflows that require a wide WHO/ISS PCB coverage in one defined concentration level for efficient analytical setup.

Questions about WHO/ISS PCB Solution ROTI®Star, 32 PCBs 10 µg/ml in isooctane, 1 ml
What is this article?
WHO/ISS PCB Solution ROTI®Star, 32 PCBs 10 µg/ml in isooctane, 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 Lab chemicals.
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 Lab chemicals.
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.
