Description
PCB 81 is a defined polychlorinated biphenyl congener in the ROTI®Star range for environmental analysis and gas chromatography. It is identified by CAS number 70362-50-4 and the empirical formula C₁₂H₆Cl₄, with a molar mass of 291,99 g/mol, and belongs to the tetrachlorobiphenyl group used as reference material in residue and contamination studies. Each unit supplies 10 mg of the compound in glass, a practical format for preparing stock and working solutions under controlled laboratory conditions. Analytical laboratories employ individual PCB congeners of this type when developing, validating or routinely running GC methods for environmental samples and related matrices. The material from manufacturer Carl ROTH supports clear congener assignment and quantitative calibration where reliable identity of PCB 81 is required. Within multi-analyte PCB schemes, discrete standards help confirm peak identity, establish response factors and maintain method performance. This ROTI®Star preparation is intended for professional chromatographic and environmental testing applications that depend on well-specified reference substances.

Questions about PCB 81, ROTI®Star, 10 mg, glass
What is this article?
PCB 81, 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.
