Acetonitrile gradient grade for liquid chromatography LiChrosolv® Reag. Ph Eur
Acetonitrile gradient grade for liquid chromatography LiChrosolv® Reag. Ph Eur
This product is currently out of stock and unavailable.
Description
| Catalogue Number | 100030 |
| Synonyms | ACN, Methyl cyanide, Ethyl nitrile, Cyanomethane |
| 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. |
