Deskripsi Merck METHANOL GRADIENT GRADE FOR LIQUID CHROM

106007 Methanol Methanol gradient grade for liquid chromatography LiChrosolv® Reag. Ph Eur. CAS 67-56-1, chemical formula CH₃OH, molar mass 32.04 g/mol.

atau disebut juga : MeOH, Hydroxymethane, Methyl alcohol, Carbinol

With their high degree of UV transmittance, low particle count, low acidity and alkalinity and low evaporation residue level, LiChrosolv® solvents are ideal for reproducible separations. Since separations are normally carried out under gradient conditions in analytical HPLC, we offer solvents in "gradient grade" as well as "isocratic grade". This enables to minimize the gradient effect of the solvent involved.
