MERCK 108101.1000 Tetrahydrofuran For Liquid Chromatography Lichrosolv® UN2056 3, II CAS No.109-99-9
| Description |
|---|
| Catalogue Number | 108101 |
| Synonyms | THF, Tetramethylene oxide, Oxolane, Butylene oxide |
| Overview | 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. |
