General description

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 done under gradient conditions in analytical HPLC, we offer solvents in "gradient grade" and "isocratic grade". This enables to minimize the gradient effect of the solvent involved.

Application

Acetonitrile is used as:
  • A solvent for the mobile phase during the solid phase extraction (SPE) for the preconcentration of Bisphenol A (BPA) from tea samples.
  • An extraction solvent for volatile organic compounds from concentrated indoor air samples.
  • A rinsing solvent for glassware.

HPTLC was used to analyze caffeine in coffee. Filtration of coffee through a PTFE syringe filter was the only sample preparation. Quantitation was conducted with a TLC scanner.

Sildenafil, sold under the brand name Viagra, among others, is a medication used to treat erectile dysfunction and pulmonary arterial hypertension.

This paper illustrates the setting up of a Lopinavir assay following European pharmacopoeia guidelines (10.2), and using a shorter column packed with smaller particles. The described assay saves valuable time and improves separation efficiency, which typically translates to better method performance.
