詳細

詳細

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.

アプリケーション

Methanol is used as a solvent:

• In the mobile phase to separate mercury species on a Zorbax C18 reverse phase column.
• To wash the cartridges and as an eluent to extract the analytes during the solid-phase extraction (SPE) process.
