Description
PCB 19 is a polychlorinated biphenyl congener reference material in the ROTI®Star range for environmental analysis and chromatographic use. Identified by CAS number 38444-73-4 and empirical formula C₁₂H₇Cl₃, it has a molar mass of 257,54 g/mol and is offered as a 10 mg pack in glass. The material supports gas chromatography and allied techniques employed to establish retention data, response factors and recovery in PCB monitoring. This congener from manufacturer Carl ROTH is appropriate for calibration, method development and quality-control routines in environmental and analytical laboratories. The small glass pack provides a practical amount for preparing stock and working standards while limiting excess holdings of chlorinated aromatic references. PCB 19 serves laboratories that need a defined trichlorobiphenyl standard for chromatography-based environmental analysis. Handle under good laboratory practice for chlorinated aromatics and consult the safety data sheet for complete hazard and handling information before use.

Questions about PCB 19, ROTI®Star, 10 mg, glass
What is this article?
PCB 19, ROTI®Star, 10 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.
Which category should I open next?
