Description
PCB 128 is a polychlorinated biphenyl reference solution supplied at 500 µg/ml in isooctane for environmental and chromatographic work. Offered as a ROTI®Star preparation from manufacturer Carl ROTH, this single-congener standard supports gas chromatography and related environmental analysis where defined PCB levels are required for calibration, method development, or quality control. The solution is filled in a 1 ml glass unit, suited to precise handling of small analytical aliquots. Physical data for the preparation include a density of 0,69 g/cm³, a flash point of −12 °C, and a boiling point of 99,2 °C; the material is assigned UN number 1262. Laboratories engaged in residue monitoring, environmental screening, and GC-based PCB determination can integrate this ready-to-use isooctane solution into established workflows without further dilution steps when the stated concentration matches the method design. Clear labelling of the congener identity and concentration helps maintain traceability across sample sequences and instrument runs.
This article is part of Chromatography standards (GC, HPLC, pesticides), in Analytical standards & reference materials.

Questions about PCB 128, 500 µg/ml in isooctane, 1 ml, glass
What is this article?
PCB 128, 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 Chromatography standards (GC, HPLC, pesticides), inside Analytical standards & reference materials, in Lab chemicals.
A chromatography standard is the substance, or the mix, injected so a peak can be named and quantified. Pesticide mixes, residual-solvent mixes and single-compound standards are different articles. The concentration and the solvent are the specification. The solvent has to be one the method may contain.
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.
