Description
PCB 90 is a defined polychlorinated biphenyl congener provided as a ROTI®Star reference standard for gas-chromatographic and environmental analytical methods. It is characterised by CAS number 68194-07-0, empirical formula C₁₂H₅Cl₅ and molar mass 326,43 g/mol, enabling unambiguous chemical identification in calibration and confirmation work. Supplied as 10 mg in glass, the solid quantity supports repeated preparation of stock and intermediate solutions for multi-point calibrations. Environmental testing laboratories rely on individual PCB congeners such as PCB 90 to map residue profiles, verify chromatographic separation and document method accuracy in soil, sediment, water and biota extracts. Single-congener standards complement technical mixtures by allowing targeted quantification and clearer peak assignment in complex chromatograms. This ROTI®Star material from manufacturer Carl ROTH is aimed at laboratories performing congener-specific PCB analysis under established GC workflows. The glass pack format facilitates secure storage and controlled aliquoting of the reference solid in daily laboratory practice.
This article is part of ICP, AAS & ion standards, in Analytical standards & reference materials.

Questions about PCB 90, ROTI®Star, 10 mg, glass
What is this article?
PCB 90, ROTI®Star, 10 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.
