Description
PCB 138 is a hexachlorobiphenyl congener supplied as a ROTI®Star analytical reference material for chromatography and environmental laboratories. It is specified with CAS number 35065-28-2, empirical formula C₁₂H₄Cl₆ and a molar mass of 360,88 g/mol, giving a clear molecular identity for congener-specific work. The preparation is packed as 10 mg in glass, providing a convenient quantity for calibration solutions, spiking experiments and method validation. PCB 138 is frequently used in gas chromatography workflows that resolve and quantify individual polychlorinated biphenyls in environmental samples. Discrete congener standards help establish retention times, response factors and confirmation criteria when complex PCB patterns are analysed. This reference material is available from manufacturer Carl ROTH within the ROTI®Star portfolio for environmental analysis and GC applications. Its defined composition, practical glass pack size and alignment with chromatographic practice support reliable use in research, monitoring and quality-control settings that depend on well-characterised PCB standards.
This article is part of ICP, AAS & ion standards, in Analytical standards & reference materials.

Questions about PCB 138, ROTI®Star, 10 mg, glass
What is this article?
PCB 138, 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.
