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.
