Description
PCB 32 is a trichlorobiphenyl reference material in the ROTI®Star range, intended for analytical and chromatographic work. Identified by CAS number 38444-77-8 and empirical formula C₁₂H₇Cl₃, it has a molar mass of 257,54 g/mol and is supplied as a 10 mg portion in glass. This congener supports calibration, method development and quality control in gas chromatography when laboratories quantify polychlorinated biphenyls in environmental and residue matrices. Defined single-congener standards help assign peaks, establish response factors and verify separation performance in GC workflows used for persistent organic pollutant monitoring. The product is available from manufacturer Carl ROTH within the ROTI®Star portfolio for environmental analysis and chromatography. The neat 10 mg pack size is practical for preparing stock and working solutions under controlled laboratory conditions. PCB 32 is applied in environmental surveillance, research and routine testing programmes that require congener-specific identification rather than bulk Aroclor-type mixtures, supporting consistent analytical results across GC-based methods.

Questions about PCB 32, ROTI®Star, 10 mg, glass
What is this article?
PCB 32, 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.
Which category should I open next?
