Description
PCB 71 is a tetrachlorobiphenyl reference standard supplied in the ROTI®Star line for environmental analysis and gas chromatography. With CAS number 41464-46-4, empirical formula C₁₂H₆Cl₄, and molar mass 291,99 g/mol, it provides a chemically defined congener for calibration and identification tasks. The product is packed as 10 mg in glass, a convenient format for preparing working standards and verification solutions in analytical laboratories. Individual PCB congeners are widely applied in environmental residue programmes, method development, and chromatographic quality control where unambiguous reference materials are essential. This preparation from manufacturer Carl ROTH supports GC-based workflows that quantify or confirm polychlorinated biphenyls in complex matrices. Typical uses include establishment of retention references, multi-point calibrations, and routine performance checks on gas-chromatographic systems. The glass pack helps maintain sample integrity during laboratory handling of small analytical quantities for environmental and chromatography applications.

Questions about PCB 71, ROTI®Star, 10 mg, glass
What is this article?
PCB 71, 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.
