Description
PCB 48 is a polychlorinated biphenyl congener offered as a ROTI®Star reference material for analytical chemistry. Identified by CAS number 70362-47-9 and empirical formula C₁₂H₆Cl₄, this tetrachlorobiphenyl has a molar mass of 291,99 g/mol and serves as a defined standard in instrumental analysis. The product is supplied in a 5 mg glass pack sized for calibration work, spike recovery studies and routine quality control. Environmental laboratories use individual PCB congeners when building calibration curves or confirming peak identity in gas chromatography. Applications span environmental analysis and chromatography workflows where reliable reference substances underpin quantitative results. Material from manufacturer Carl ROTH in the ROTI®Star series supports method development for residue determination in soils, sediments, biota and related matrices. Analysts can deploy PCB 48 as a single-component standard or incorporate it into multi-congener mixtures according to laboratory protocols. The glass packaging facilitates precise weighing and preparation of stock solutions under controlled conditions. Consistent identity data including EG number 690-319-7 help documentation within regulated testing environments.

Questions about PCB 48, ROTI®Star, 5 mg, glass
What is this article?
PCB 48, 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.
