Description
PCB 197 is a polychlorinated biphenyl congener supplied as a ROTI®Star reference material for environmental and chromatographic analysis. With CAS number 33091-17-7 and empirical formula C₁₂H₂Cl₈, this octachlorobiphenyl has a molar mass of 429,77 g/mol and serves laboratories that need defined PCB standards for calibration, peak assignment, and quantitative work. It is particularly relevant to gas chromatography methods used in monitoring persistent organic pollutants. Packaged as 5 mg in glass, the neat material supports flexible preparation of stock and dilution series under laboratory-controlled conditions. PCB 197 from manufacturer Carl ROTH belongs to the ROTI®Star range and is aimed at professional users in environmental analysis, residue testing, and related GC applications. Documented identity parameters assist traceability when laboratories assemble multi-congener calibration mixes or check separation performance for highly chlorinated biphenyls. This reference substance integrates readily into routine quality-control schemes and research protocols that depend on discrete, well-characterised PCB congeners for reliable analytical results.

Questions about PCB 197, ROTI®Star, 5 mg, glass
What is this article?
PCB 197, ROTI®Star, 5 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.
