Description
PCB 94 is a polychlorinated biphenyl congener supplied as an analytical reference material, with CAS number 73575-55-0 and empirical formula C₁₂H₅Cl₅. It is presented in the ROTI®Star line and has a molar mass of 326,43 g/mol, suitable for laboratories that require defined PCB standards. The pack contains 5 mg in glass, enabling preparation of concentrated stocks and diluted calibration levels for chromatographic work. Environmental analysis programmes use individual congeners to track persistent organic pollutants and to verify selectivity in complex sample extracts. In gas chromatography, PCB 94 supports method development, retention-time assignment and multi-component calibration schemes typical of residue and environmental testing. This material from manufacturer Carl ROTH is intended for professional analytical settings where consistent reference substances underpin data quality. The small glass unit facilitates precise handling during weighing and dissolution while fitting the scale of standard preparation common in GC-based PCB workflows.
This article is part of ICP, AAS & ion standards, in Analytical standards & reference materials.

Questions about PCB 94, ROTI®Star, 5 mg, glass
What is this article?
PCB 94, 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.
