Beschrijving
Petroleum, speciale fractie 130–180 °C, is een geraffineerde koolwaterstofoplosmiddelfractie die wordt gedefinieerd door een gecontroleerd kooktraject van 130 tot 180 °C. Het draagt CAS-nummer 64742-82-1 en EG-nummer 927-344-2, met een dichtheid van 0.776 g/cm³ en een vlampunt van 29 °C. Fysische gegevens van fabrikant Carl ROTH omvatten het vermelde kookinterval, de dichtheid en het vlampunt, ter ondersteuning van reproduceerbare hantering en risicobeoordeling in chemische werkstromen. Het materiaal wordt geïdentificeerd onder UN-nummer 1300 voor de transportclassificatie. De gedefinieerde fractie maakt het nuttig waar een smaller kookgedrag dan algemene petroleum spirit de voorkeur heeft.

Questions about Petroleum , speciale fractie 130-180 °C, 1 l, glas
What is this article?
Petroleum , speciale fractie 130-180 °C, 1 l, glas is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Chromatografiestandaarden (GC, HPLC, pesticiden), inside Analytische standaarden & referentiematerialen, in Chemicaliën.
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.
