Description
PCB 31 is a polychlorinated biphenyl congener reference solution prepared at 500 µg/ml in isooctane for quantitative chromatographic analysis. As part of the ROTI®Star range, this higher-concentration standard is suited to environmental analysis, residue testing and gas chromatography applications that require reliable PCB identification and quantification. It is supplied in a 1 ml glass pack, ready for dilution into calibration series, system checks and laboratory quality-control schemes. The isooctane matrix shows a density of 0,69 g/cm³, a flash point of -12 °C and a boiling point of 99,2 °C, information that supports safe handling and method setup on GC systems. Analysts employ such defined congener solutions to build response factors, confirm retention windows and verify performance when monitoring polychlorinated biphenyls in environmental matrices. The product comes from manufacturer Carl ROTH and integrates smoothly into routine GC workflows and method-development work. Its stated concentration and solvent matrix help laboratories maintain consistent, comparable calibration practices across screening and confirmatory analyses.
This article is part of Chromatography standards (GC, HPLC, pesticides), in Analytical standards & reference materials.

Questions about PCB 31, 500 µg/ml in isooctane, 1 ml, glass
What is this article?
PCB 31, 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.
Which category should I open next?
