Description
PCB 79 is a tetrachlorobiphenyl reference congener from the ROTI®Star line for environmental analysis and gas chromatography. It carries CAS number 41464-48-6 and the empirical formula C₁₂H₆Cl₄, with a molar mass of 291,99 g/mol, making it suitable for congener-specific calibration and identification tasks. Each pack provides 10 mg of material in glass, a convenient quantity for preparing stock solutions and working standards under laboratory conditions. Analytical groups apply individual PCB congeners when setting up, validating or running GC methods for environmental and related sample types. The product from manufacturer Carl ROTH supports reliable assignment of PCB 79 within complex chromatograms and multi-residue schemes. Discrete standards of this kind assist laboratories in establishing retention data, response factors and ongoing method control. This ROTI®Star preparation is intended for professional chromatographic and environmental testing work that depends on clearly specified polychlorinated biphenyl reference substances.

Questions about PCB 79, ROTI®Star, 10 mg, glass
What is this article?
PCB 79, ROTI®Star, 10 mg, glass 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.
