? Outstanding wettability (even for 100% aqueous visualisation reagents)
? Easy and precise cutting (no flaking of silica)
? Excellent separation efficiency and reproducibility from batch to batch
Silica gel, highly porous textured matrix are generally used for synthesis of adsorbents. They are corpuscular in structure. Silica surface possess a layer of hydroxyl groups and adsorbed water molecules, which can be removed by drying at high temperature or even by treatment with suitable reagents. Silica gel surface plays important role in catalysis, chemical separation and microelectronic fabrications. Aluminium sheets precoated with silica gel, are used as stationary phase in TLC.
TLC Al foils may be used for Thin layer chromatography.
