Description
PCB 93 is a defined polychlorinated biphenyl congener supplied as a ROTI®Star reference material for environmental and chromatographic work. It carries CAS number 73575-56-1, the empirical formula C₁₂H₅Cl₅ and a molar mass of 326,43 g/mol, giving laboratories a clear chemical identity for calibration and identification tasks. The compound is packed as 5 mg in glass, a convenient solid quantity for preparing stock and working solutions used in gas-chromatographic methods. Within environmental analysis programmes, PCB 93 supports congener-specific monitoring of polychlorinated biphenyls in matrices such as soil, sediment, water and biota extracts. Method development, instrument qualification and routine quality control all benefit from a well-characterised individual congener rather than complex technical mixtures. This ROTI®Star grade material from manufacturer Carl ROTH is intended for analytical laboratories that require traceable PCB standards for GC-based workflows. Handling follows standard laboratory practice for chlorinated aromatic compounds, and the glass primary packaging helps protect the solid during storage and aliquoting.

Questions about PCB 93, ROTI®Star, 5 mg, glass
What is this article?
PCB 93, 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.
