General description

LiChrosolv® solvents have high degree of UV transmittance, low particle count, low acidity and alkalinity and low evaporation residue level. This makes them ideal for reproducible separations.

Application

Used as a solvent in chromatography applications.
Also featured in USP monograph methods for regulated pharmaceutical instrumental analysis.

Features and Benefits

  • packaged in glass bottles
  • offers high resolution, sensitivity and optimized peak baseline separation
