WebSilica gel is a suitable adsorbent for water, alcohol, phenols, amines, and so on. That does this through hydrogen bonds. The adsorption capacity of silica gel at low temperatures is … WebDNA binds to silica under high salt conditions, and releases from silica under low salt conditions. This is why binding buffers are made with salts and DNA elution buffers do not contain salt. Larger fragments are more difficult to elute because they bind more tightly to the column’s matrix. chipworks telWebgested that the water evolved during calcination of silica gel, besides physically adsorbed water, is formed from OH groups that are chemically held on the silica surface.
