Description
PCB 194 is a polychlorinated biphenyl congener offered as a ROTI®Star reference material for environmental analysis and gas chromatography. Identified by CAS number 35694-08-7 and empirical formula C₁₂H₂Cl₈, this octachlorobiphenyl has a molar mass of 429,77 g/mol and is used when laboratories require defined PCB standards for calibration, compound confirmation, and quantitative measurements. It is suited to chromatographic methods targeting persistent organic pollutants and related residue applications. Supplied as 5 mg in glass, the neat solid allows controlled preparation of stock and working solutions in line with laboratory protocols. PCB 194 from manufacturer Carl ROTH forms part of the ROTI®Star range and is directed at professional users in environmental monitoring, method validation, and quality-control settings. Documented identity data support traceability when assembling multi-congener calibration mixtures or assessing separation of highly chlorinated biphenyls. This reference substance fits routine and research workflows that depend on reliable, discrete PCB congener materials for consistent analytical performance.

Questions about PCB 194, ROTI®Star, 5 mg, glass
What is this article?
PCB 194, 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.
