Questions about Methanol, min. 99,5 %, Ph.Eur., extra puur, 1 l, glas
What is this article?
Methanol, min. 99,5 %, Ph.Eur., extra puur, 1 l, glas is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Oplosmiddelen van technische & synthesekwaliteit, inside Oplosmiddelen, in Chemicaliën.
Technical and synthesis grades are for cleaning, for a coarse extraction and for chemistry that does not end in a chromatogram. They cost less because more impurity is allowed. They are the wrong bottle to make a mobile phase or a volumetric standard.
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?
