Description
PCB 20 is a polychlorinated biphenyl reference standard at 100 µg/ml in isooctane for environmental analysis and gas chromatography. This ROTI®Star preparation is filled as a 1 ml glass unit and supports calibration curves, quality-control spikes and quantitative determination of the PCB 20 congener. Physical characteristics 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, together with UN number 1262. Laboratories can use these values when planning solvent handling, ventilation needs and chromatographic run conditions. The solution from manufacturer Carl ROTH is appropriate where a moderate stock concentration simplifies multi-point calibration or reduces the risk of overloading sensitive detectors. The compact 1 ml glass pack size is convenient for controlled consumption and orderly storage of individual PCB congener standards. It is aligned with environmental analysis, chromatography and gas chromatography applications that specify PCB 20 at 100 µg/ml in isooctane.
This article is part of ICP, AAS & ion standards, in Analytical standards & reference materials.

Questions about PCB 20, 100 µg/ml in isooctane, 1 ml, glass
What is this article?
PCB 20, 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 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?
