Description
PCB 39 is a polychlorinated biphenyl congener offered as a ROTI®Star reference material for analytical and environmental laboratories. It is characterised by CAS number 38444-88-1, empirical formula C₁₂H₇Cl₃ and a molar mass of 257,54 g/mol, giving a well-defined identity for standard preparation. The product is supplied as 10 mg in glass, convenient for preparing calibration solutions and for use in targeted congener analysis. Available in the ROTI®Star assortment from manufacturer Carl ROTH, PCB 39 is intended for applications in environmental analysis, chromatography and especially gas chromatography, where individual PCB standards are essential. Analysts rely on such materials for method validation, quantitative determination and quality assurance when monitoring chlorinated biphenyls. The small glass pack supports careful handling of the solid substance and efficient use in routine GC workflows as well as specialised research protocols requiring discrete PCB congeners.
This article belongs on ICP, AAS & ion standards, in Analytical standards & reference materials.

Questions about PCB 39, ROTI®Star, 10 mg, glass
What is this article?
PCB 39, 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.
