Description
PCB 33 is a defined trichlorobiphenyl congener supplied as ROTI®Star reference material for gas chromatography and environmental analysis. It is characterised by CAS number 38444-86-9, empirical formula C₁₂H₇Cl₃ and a molar mass of 257,54 g/mol (EG nr. 684-563-3). The product is delivered as 10 mg in glass, offering a neat solid that laboratories can weigh and dissolve to prepare stock solutions, calibration curves and matrix spikes. Congener-specific standards such as PCB 33 are essential for identifying and quantifying polychlorinated biphenyls in complex environmental extracts and for checking chromatographic selectivity under GC or GC-MS conditions. Manufacturer Carl ROTH provides this item within the ROTI®Star line, a range established for individual PCB standards used in monitoring and research. The solid format supports accurate gravimetric handling and flexible combination with other congeners into multi-level mixes. PCB 33 is therefore well suited to soil, sediment, water and biota testing programmes that require reliable, single-congener reference points.
This article is part of ICP, AAS & ion standards, in Analytical standards & reference materials.

Questions about PCB 33, ROTI®Star, 10 mg, glass
What is this article?
PCB 33, 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.
