Description
PCB 8 is a defined polychlorinated biphenyl congener supplied as a ROTI®Star reference material for demanding analytical work. With CAS number 34883-43-7, empirical formula C₁₂H₈Cl₂ and a molar mass of 223,10 g/mol, this dichlorobiphenyl standard supports precise identification and quantification in chromatographic methods. The material is offered in a 25 mg glass pack, suited to calibration, method development and confirmatory analysis where a discrete PCB congener is required. Laboratories engaged in environmental analysis and gas chromatography rely on such individual congeners to build calibration series, verify retention behaviour and assess recovery in complex matrices. PCB 8 from manufacturer Carl ROTH fits workflows that call for well-characterised single-congener standards rather than technical mixtures. Its defined molecular identity and compact pack size make it practical for reference libraries, proficiency testing preparations and routine GC-based monitoring of polychlorinated biphenyls in environmental and related sample types, while remaining easy to handle and aliquot under controlled laboratory conditions.
This article is part of ICP, AAS & ion standards, in Analytical standards & reference materials.

Questions about PCB 8, ROTI®Star, 25 mg, glass
What is this article?
PCB 8, ROTI®Star, 25 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.
