Description
Methanol ROTISOLV® is a high-purity solvent graded min. 99,98 % for Ultra LC-MS applications and specified for PFAS analysis. It is identified by CAS number 67-56-1 and empirical formula CH₃OH, with a molar mass of 32,04 g/mol, density of 0,79 g/cm³, flash point of 9,7 °C and boiling point of 65 °C. Supplied in a 1 l pack, this grade suits liquid-chromatography–mass-spectrometry methods that demand very low impurity levels and consistent solvent performance. Analytical laboratories running PFAS protocols and other Ultra LC-MS assays can use this methanol where blank contribution and spectral cleanliness are critical. The product from manufacturer Carl ROTH is further referenced by EG number 200-659-6, supporting documentation and compliance tracking. Stated physical data help with method development, instrument conditioning and safe handling in routine and research analytical chemistry settings focused on sensitive detection.

Questions about Methanol, ROTISOLV®, min. 99,98 %, Ultra LC-MS, for PFAS analysis
What is this article?
Methanol, ROTISOLV®, min. 99,98 %, Ultra LC-MS, for PFAS analysis 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.
