Description
PCB 209 is a polychlorinated biphenyl reference solution at 100 µg/ml (related to Cl) in n-hexane, intended for environmental analysis and gas chromatography. The analyte corresponds to the empirical formula C₁₂Cl₁₀ and is offered under the ROTI®Star designation. Matrix properties include a density of 0,66 g/cm³, a flash point of −22 °C and a boiling point of 68 °C for the n-hexane solvent system. Supplied in a 1 ml glass pack, the higher concentration supports flexible dilution schemes for calibration curves, spike recovery and instrument performance checks. Congener PCB 209 is a common reference point in environmental monitoring and chromatographic methods that require a fully chlorinated biphenyl standard. This preparation comes from manufacturer Carl ROTH for laboratories working in environmental analysis, residue testing and GC applications. The compact glass format suits controlled handling of the volatile n-hexane solution and facilitates accurate preparation of working standards in routine and method-validation settings.
This article belongs on HPLC & LC-MS grade solvents, in Solvents. See also Analytical grade solvents (p.a.).

Questions about PCB 209, 100 µg/ml (related to Cl) in n-hexane, 1 ml, glass
What is this article?
PCB 209, 100 µg/ml (related to Cl) in n-hexane, 1 ml, glass is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in HPLC & LC-MS grade solvents, inside Solvents, in Lab chemicals.
HPLC grade limits the absorbance and the residue that would appear as peaks or baseline drift. LC-MS grade goes further on metal ions and on particles that would suppress a mass spectrum. A solvent that is only analytical grade is a false economy on an LC-MS system.
A solvent dissolves. The grade says which impurities are low enough for the method. Analytical grade is the ordinary pure solvent. HPLC and LC-MS grades limit the absorbance and the ions that would become peaks or background. A dry solvent has had water removed. A deuterated solvent is for NMR, where the hydrogen signal would otherwise drown the sample. Technical grade is for cleaning and for synthesis that does not need a chromatogram. Identity is on PubChem. Names follow IUPAC. Hazards follow ECHA, the CLP Regulation and REACH.
Which category should I open next?
The category is Solvents. The sub-category is HPLC & LC-MS grade solvents. The catalogue is Lab chemicals.
Shelves beside this one are Analytical grade solvents (p.a.), Dry & deuterated solvents (NMR, synthesis), Technical & synthesis grade solvents and Green & alternative solvents.
What should I check before I order?
The technical information on this page is the manufacturer's sheet. Read that, not a rewritten specification.
When this page shows a safety data sheet, use that manufacturer file. Hazard text does not belong in the sales description. For a pack size, a grade or a certificate that is not on the page, send a quote request or contact the team.
