Description
PCB 148 is a hexachlorobiphenyl congener reference material from the ROTI®Star line, designed for precise analytical work in environmental and gas-chromatography laboratories. It carries CAS number 74472-41-6, empirical formula C₁₂H₄Cl₆ and a molar mass of 360,88 g/mol, giving a well-defined basis for identification and quantification. Supplied as 5 mg in glass, the neat standard supports preparation of calibration solutions, spikes and control samples. Congener-specific PCB references are widely used when laboratories assess persistent organic pollutants in soil, water, sediment and biological matrices. From manufacturer Carl ROTH, PCB 148 suits method development, routine residue testing and confirmatory GC analysis where traceable PCB 148 data are required. It can stand alone for targeted checks or form part of broader multi-congener calibration sets. Apply under suitable laboratory controls according to validated procedures for environmental PCB determination and related chromatographic research applications.

Questions about PCB 148, ROTI®Star, 5 mg, glass
What is this article?
PCB 148, ROTI®Star, 5 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.
