Description
PCB 135 is a hexachlorobiphenyl congener reference material from the ROTI®Star line, intended for demanding analytical work. Identified by CAS number 52744-13-5 and empirical formula C₁₂H₄Cl₆, it has a molar mass of 360,88 g/mol and is supplied as a neat 5 mg portion in glass. Laboratories use this defined PCB congener in environmental analysis and gas chromatography for calibration, peak assignment, and multi-congener method development. Packed for precise handling of small analytical quantities, the standard supports qualitative confirmation and quantitative response work on residues in environmental matrices. Offered by manufacturer Carl ROTH, PCB 135 fits GC workflows where individual congener identity matters for monitoring programmes and chromatographic validation. The material is suited to building or extending calibration sets alongside related PCB standards, helping analysts establish reliable retention behaviour and response factors under routine GC conditions. It is aimed at professional laboratories that require clearly specified polychlorinated biphenyl reference substances for environmental and chromatographic applications.
This article is part of ICP, AAS & ion standards, in Analytical standards & reference materials.

Questions about PCB 135, ROTI®Star, 5 mg, glass
What is this article?
PCB 135, 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.
