Description
PCB 121 is a ready-to-use analytical standard solution at 100 µg/ml in isooctane, presented as 1 ml in glass for environmental and chromatographic laboratories. Part of the ROTI®Star assortment from manufacturer Carl ROTH, this congener reference supports gas chromatography applications in environmental analysis of polychlorinated biphenyls. The solution is characterised by a density of 0,69 g/cm³, a flash point of -12 °C and a boiling point of 99,2 °C, together with UN number 1262 for the isooctane matrix. At 100 µg/ml the concentration is convenient for direct use in calibration, system checks and spike experiments without extensive intermediate dilution. Laboratories running multi-residue PCB methods can rely on clear congener identity when building calibration sets or verifying detector response. The small 1 ml glass pack size enables accurate aliquoting and reduces surplus material in routine workflows. Physical parameters of the solvent system help users plan safe handling within GC-focused environmental testing environments.
This article is part of Chromatography standards (GC, HPLC, pesticides), in Analytical standards & reference materials.

Questions about PCB 121, 100 µg/ml in isooctane, 1 ml, glass
What is this article?
PCB 121, 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.
