Description
PCB 90 is a polychlorinated biphenyl congener standard supplied at 500 µg/ml in isooctane for environmental analysis and gas chromatography. This higher-concentration ROTI®Star solution from manufacturer Carl ROTH is suited to calibration stock preparation, spiking experiments and quantitative GC work where a more concentrated single-congener reference is advantageous. Filled as 1 ml in glass, it presents a density of 0,69 g/cm³, flash point −12 °C and boiling point 99,2 °C, corresponding to the isooctane matrix (UN 1262). Laboratories use PCB 90 standards in residue studies, pollution assessment and method validation that require traceable congener-level response. The 500 µg/ml strength allows flexible dilution to working levels while limiting solvent carry-over into analytical sequences. Compact glass packaging supports orderly bench handling and storage for chromatography and environmental applications that depend on well-defined PCB reference materials.
This article is part of ICP, AAS & ion standards, in Analytical standards & reference materials.

Questions about PCB 90, 500 µg/ml in isooctane, 1 ml, glass
What is this article?
PCB 90, 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 ICP, AAS & ion standards, inside Analytical standards & reference materials, in Lab chemicals.
An ICP, AAS or ion standard is a solution of a stated element or ion at a stated concentration, with an uncertainty. It is the calibration point of a spectrometer or an electrode. The matrix, often dilute acid, has to match the method. A standard past its expiry is not that concentration.
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?
