Description
PCB 99 is a defined polychlorinated biphenyl congener in the ROTI®Star range, intended for environmental analysis and gas chromatography. It is specified by CAS number 38380-01-7, empirical formula C₁₂H₅Cl₅, molar mass 326,43 g/mol and EG nr. 690-177-6. Supplied as 5 mg in glass, the material supports preparation of reference solutions for calibration, identification and performance checks in GC-based PCB determinations. Analytical teams use individual congener standards when characterising complex environmental matrices and when confirming chromatographic behaviour of target PCBs. Available from manufacturer Carl ROTH, this glass-packed unit is practical for stock and working-solution preparation in residue and contamination laboratories. Clear chemical descriptors facilitate traceable documentation in method development and routine quality control. The 5 mg pack size matches common laboratory needs for sensitive chromatographic applications involving discrete PCB congeners.
This article is part of ICP, AAS & ion standards, in Analytical standards & reference materials.

Questions about PCB 99, ROTI®Star, 5 mg, glass
What is this article?
PCB 99, ROTI®Star, 5 mg, 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.
