Application Note

Silica gel 60 (35–70 µm) is used as a bulk adsorbent for preparative and flash column chromatography. The irregular silica particles have a controlled 35–70 µm particle-size range, equivalent to approximately 200–400 mesh ASTM, and provide high adsorptive capacity with good permeability for packed columns. The material has a BET surface area of approximately 480–540 m²/g and a pore volume around 0.74–0.84 mL/g. Its chemically inert inorganic surface supports normal-phase separation of compounds with different polarities and can also be used as a drying or moisture-control material in suitable laboratory applications. This configuration is supplied as a 25 kg package, making it appropriate for laboratories and process-development groups that perform frequent or larger-scale preparative chromatographic separations.
