Description
PCB 34 is a polychlorinated biphenyl congener standard presented at 500 µg/ml in isooctane for gas chromatography and environmental analysis. This ROTI®Star solution from manufacturer Carl ROTH comes in a 1 ml glass pack sized for analytical calibration and control sample preparation. Characteristic properties of 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, with UN number 1262. Laboratories apply PCB 34 when building congener-specific calibration sets, verifying chromatographic separation and quantifying PCB residues by GC or GC-MS. The fixed concentration enables rapid preparation of intermediate and working standards without weighing neat material, supporting reproducible spike and recovery experiments. Glass packaging is suited to organic reference solutions used in routine and research settings. PCB 34 serves environmental monitoring, method development and quality-control programmes that require clearly identified single-congener references for accurate peak assignment and quantitative reporting.
This article is part of Chromatography standards (GC, HPLC, pesticides), in Analytical standards & reference materials.

Questions about PCB 34, 500 µg/ml in isooctane, 1 ml, glass
What is this article?
PCB 34, 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?
