Description
PCB 128 is a hexachlorobiphenyl congener supplied as a ROTI®Star reference solid for environmental and chromatographic analysis. It is defined by CAS number 38380-07-3, empirical formula C₁₂H₄Cl₆ and a molar mass of 360,88 g/mol, supporting accurate congener identification in GC and GC-MS methods. Packaged as 25 mg in glass, the unit offers a practical quantity for preparing calibration stocks, working standards and quality-control solutions. This PCB 128 material from manufacturer Carl ROTH is suited to gas chromatography applications in laboratories that profile polychlorinated biphenyls in environmental, industrial or regulatory samples. Analysts can use the congener to extend multi-level calibrations, confirm retention behaviour and strengthen method validation for hexachlorinated species. The ROTI®Star line focuses on clearly specified single-congener reagents for residue and pollution monitoring. With documented molecular data and a glass presentation, the product fits routine screening, confirmatory analysis and research programmes that require discrete PCB 128 as part of a broader congener set.

Questions about PCB 128, ROTI®Star, 25 mg, glass
What is this article?
PCB 128, ROTI®Star, 25 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?
