Description
PCB 74 is a single-congener polychlorinated biphenyl standard offered as a 500 µg/ml solution in isooctane for analytical and environmental laboratory use. Belonging to the ROTI®Star range, this reference preparation supports gas chromatography and related chromatographic methods where a higher-concentration PCB 74 stock is useful for calibration, spiking and method verification. The material is filled in a 1 ml glass container, providing a compact pack size suited to controlled dilution into working standards. Reported physical data include a density of 0,69 g/cm³, a flash point of −12 °C and a boiling point of 99,2 °C, reflecting the isooctane solvent system (UN number 1262). Environmental analysis teams and chromatography laboratories can employ this standard from manufacturer Carl ROTH when establishing quantitative PCB 74 responses or preparing multi-level calibration series. The 500 µg/ml concentration offers flexibility for serial dilution while keeping the neat stock volume modest. Glass packaging aids secure storage and transfer under typical laboratory handling practices for flammable organic solutions used in GC-based PCB work.
This article is part of Chromatography standards (GC, HPLC, pesticides), in Analytical standards & reference materials.

Questions about PCB 74, 500 µg/ml in isooctane, 1 ml, glass
What is this article?
PCB 74, 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.
