Description
PCB 7 is a single-congener polychlorinated biphenyl reference solution at 100 µg/ml in isooctane, prepared for environmental analysis and gas chromatography. This ROTI®Star standard is supplied as a 1 ml glass pack, giving laboratories a defined concentration for calibration, recovery checks and quantitative QC work. Physical data for the isooctane matrix include a density of 0,69 g/cm³, a flash point of −12 °C and a boiling point of 99,2 °C; the preparation is classified under UN number 1262 and must be handled as a flammable liquid. In residue and contaminant testing, PCB 7 standards support peak identification, response-factor determination and method validation on GC systems. The solution from manufacturer Carl ROTH fits routine environmental monitoring workflows where a reliable mono-congener level in isooctane is required. Use under controlled laboratory conditions with appropriate solvent-compatible glassware and GC-compatible injection practices to maintain analytical integrity throughout calibration sequences.
This article belongs on Chromatography standards (GC, HPLC, pesticides), in Analytical standards & reference materials.

Questions about PCB 7, 100 µg/ml in isooctane, 1 ml, glass
What is this article?
PCB 7, 100 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?

What should I check before I order?
The technical information on this page is the manufacturer's sheet. Read that, not a rewritten specification.
When this page shows a safety data sheet, use that manufacturer file. Hazard text does not belong in the sales description. For a pack size, a grade or a certificate that is not on the page, send a quote request or contact the team.
