Description
PCB 23 is a polychlorinated biphenyl reference solution at 500 µg/ml in isooctane, prepared for environmental analysis and gas chromatography. Offered in the ROTI®Star line from manufacturer Carl ROTH, this standard supports calibration, method development and quantitative determination of PCB congeners in chromatographic workflows. The preparation shows a density of 0,69 g/cm³, a flash point of -12 °C and a boiling point of 99,2 °C, and is assigned UN number 1262. Supplied as a 1 ml fill in glass, it is suited to routine laboratory use where defined concentration and solvent matrix matter for reproducible GC results. Laboratories engaged in environmental monitoring, residue analysis and related chromatographic applications can integrate this congener standard into existing calibration sequences and quality-control schemes. The isooctane matrix aligns with common sample-preparation and injection practices in gas chromatography, helping maintain consistent handling across analytical runs focused on PCB determination.
This article is part of Chromatography standards (GC, HPLC, pesticides), in Analytical standards & reference materials.

Questions about PCB 23, 500 µg/ml in isooctane, 1 ml, glass
What is this article?
PCB 23, 500 µg/ml in isooctane, 1 ml, glass is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Chromatography standards (GC, HPLC, pesticides), inside Analytical standards & reference materials, in Lab chemicals.
A chromatography standard is the substance, or the mix, injected so a peak can be named and quantified. Pesticide mixes, residual-solvent mixes and single-compound standards are different articles. The concentration and the solvent are the specification. The solvent has to be one the method may contain.
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.
