Description
PCB 95 is a characterised polychlorinated biphenyl congener for analytical reference applications, identified by CAS number 38379-99-6 and empirical formula C₁₂H₅Cl₅. Part of the ROTI®Star assortment, it has a molar mass of 326,43 g/mol and is supplied as 5 mg in glass for controlled laboratory use. Such individual PCB standards are widely applied in environmental analysis when laboratories establish calibration curves, confirm peak identity or prepare fortified samples. Gas chromatography methods benefit from well-defined congeners for retention behaviour studies, multi-residue screening and ongoing system suitability checks. This PCB 95 preparation from manufacturer Carl ROTH supports research and routine testing focused on persistent organic pollutants in environmental and related matrices. The compact glass pack is practical for weighing small aliquots into volumetric glassware when building stock and working solutions. Analysts can incorporate the congener into established GC protocols for qualitative confirmation and quantitative determinations without expanding inventory beyond the required reference set.

Questions about PCB 95, ROTI®Star, 5 mg, glass
What is this article?
PCB 95, 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.
