Florisil® is a hard powdered magnesia-silica gel manufactured in the United States by U.S. Silica Company. It is often referred to as "activated magnesium silicate" or "magnesia-silica gel". As a highly selective adsorbent, Florisil® is frequently employed in the following areas of preparative and analytical chromatography:

  • Extraction of steroids, sex hormones and related compounds
  • Separation of lipids (including monoglycerides, diglycerides, triglycerides, free fatty acids, free sterols and cholesterol esters)
  • Decolourisation of fats, oils and waxes
  • Purification and isolation of alkaloid natural products by column chromatography
  • Separation of nitrogen-containing compounds from hydrocarbons
  • Cleanup of pesticide residues and purification of chlorine-containing pesticides
  • Separation of aromatic compounds from aliphatic-aromatic mixtures
  • Purification of active pharmaceutical ingredients (APIs)
  • Isolation of antibiotics
  • Assay of vitamins

 

Our Florisil® is manufactured in the United States. It it available in a variety of particle size or mesh grades that are suitable for column chromatography. The most common grades of Florisil® in academia and in industry are mesh finer than 200 (>200) and mesh 100 – 200.
