Description
PCB 55 is a tetrachlorobiphenyl congener presented as ROTI®Star material for analytical and environmental laboratory use. It carries CAS number 74338-24-2, empirical formula C₁₂H₆Cl₄ and a molar mass of 291,99 g/mol, enabling unambiguous assignment in chromatographic and confirmatory methods. Individual PCB congeners such as PCB 55 are applied in gas chromatography and environmental analysis to establish calibration points, assess recovery and characterise complex PCB patterns in environmental matrices. The product is offered in a 10 mg glass pack, giving sufficient material for repeated preparation of calibration standards, quality-control samples and method-validation experiments. Research and monitoring laboratories can use PCB 55 within multi-congener sets to compare retention behaviour and detector response under routine GC conditions. Supplied in the ROTI®Star line from manufacturer Carl ROTH, the material integrates smoothly into established analytical protocols. Documented chemical identifiers support traceability in laboratory information systems and formal reports. PCB 55 is suited to professional settings that require a defined single-congener reference for polychlorinated biphenyl determination rather than technical Aroclor-type mixtures, particularly in environmental chromatography workflows.

Questions about PCB 55, ROTI®Star, 10 mg, glass
What is this article?
PCB 55, ROTI®Star, 10 mg, glass is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Chromatography standards (GC, HPLC, pesticides), inside Analytical standards & reference materials, in Lab chemicals.
A chromatography standard is the substance, or the mix, injected so a peak can be named and quantified. Pesticide mixes, residual-solvent mixes and single-compound standards are different articles. The concentration and the solvent are the specification. The solvent has to be one the method may contain.
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.
