Description
PCB 78 is a defined polychlorinated biphenyl congener in the ROTI®Star range for environmental analysis and gas chromatography applications. Identified by CAS number 70362-49-1 and empirical formula C₁₂H₆Cl₄, it has a molar mass of 291,99 g/mol and is used as a tetrachlorobiphenyl reference material in residue and contamination studies. The unit contains 10 mg packed in glass, enabling precise preparation of analytical solutions in the laboratory. Individual PCB standards of this type are employed when laboratories develop, validate or routinely operate GC methods for environmental matrices and related samples. Material from manufacturer Carl ROTH supports clear congener identification and quantitative calibration where the identity of PCB 78 is essential. Within multi-analyte PCB methods, discrete congeners help confirm peak assignment, establish response factors and maintain analytical performance over time. This ROTI®Star product is intended for professional chromatographic and environmental testing that relies on well-specified reference compounds.
This article is part of ICP, AAS & ion standards, in Analytical standards & reference materials.

Questions about PCB 78, ROTI®Star, 10 mg, glass
What is this article?
PCB 78, 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.
