Description
PCB 7 is a polychlorinated biphenyl congener reference standard at 500 µg/ml in isooctane, intended for environmental analysis and gas chromatography. Offered in the ROTI®Star range as a 1 ml glass unit, this higher-concentration solution supports stock preparation, multi-level calibration curves and spike experiments in residue laboratories. Matrix properties include a density of 0,69 g/cm³, a flash point of −12 °C and a boiling point of 99,2 °C; the material carries UN number 1262 and requires flammable-liquid handling controls. Analytical teams use defined PCB 7 levels to establish instrument response, verify retention behaviour and strengthen quantitative methods for environmental samples. The preparation from manufacturer Carl ROTH is suited to GC workflows where a concentrated mono-congener standard in isooctane simplifies dilution schemes. Apply with solvent-compatible glassware and validated chromatographic conditions to preserve concentration accuracy from opening through to final calibration runs.
This article is part of Chromatography standards (GC, HPLC, pesticides), in Analytical standards & reference materials.

Questions about PCB 7, 500 µg/ml in isooctane, 1 ml, glass
What is this article?
PCB 7, 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.
