Methanol ≥99.9% (by GC), LiChrosolv® Reag. Ph. Eur., gradient grade for liquid chromatography, Supelco®
Methanol
- Filtered by 0,2 µm filter
- Suitable for UPLC / UHPLC / Ultra HPLC - instruments
- Conforms to Methanol R1 and R2 according to Reag. Ph. Eur.
- Conforms to the requirements of ACS for liquid chromatography suitability
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 a 'gradient grade' as well as 'isocratic grade'. This minimises the gradient effect of the solvent involved.
