Description
PCB 155 is a single-congener polychlorinated biphenyl reference from the ROTI®Star portfolio, developed for environmental analysis and gas chromatography. It carries CAS number 33979-03-2, empirical formula C₁₂H₄Cl₆ and a molar mass of 360,88 g/mol, offering a well-characterised hexachlorobiphenyl isomer for identification and quantification tasks. Supplied as 10 mg in a glass container, the standard supports accurate weighing and solution preparation for GC and GC-MS calibration and control samples. Applications include PCB congener profiling, residue monitoring and analytical quality assurance in environmental laboratories. This material from manufacturer Carl ROTH helps teams build reliable reference sets when assessing persistent organic pollutants across diverse matrices. The 10 mg glass pack is convenient for research and routine use where defined amounts of individual PCB congeners are preferred for multi-level calibrations, retention-time libraries and confirmatory measurements without surplus inventory.
This article is part of ICP, AAS & ion standards, in Analytical standards & reference materials.

Questions about PCB 155, ROTI®Star, 10 mg, glass
What is this article?
PCB 155, 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.
