Column Chromatography Silica Gel Amount at George Guerra blog

Column Chromatography Silica Gel Amount. The safest way to do this is by volume in hood. Obviously the more product you have and the closer the impurities are, the more silica gel you will need. Silica gel has a density equal to 0.5 g/ml so you can use an erlenmeyer flask to measure it out. The choice and usage of a particular silica gel mesh size for a certain type of column chromatography separation depends on a number of factors, including the type of sample that is being separated, the desired resolution that is to be achieved, and the flow rate required. Once the solvent just barely becomes level with the silica (without drying it!), another small layer of sand is applied carefully without disturbing the silica. In a separate flask or beaker, measure solvent approximately one and a half times the volume of silica. The compound mixture is dissolved. Pour the silica gel into an erlenmeyer flask. A good rule of thumb is:. For the dry method, first dissolve the sample to be analyzed in the minimum amount of solvent and add about 100 mg of silica gel. In a beaker, measure out the required amount of silica gel. The weight of the packing material should be roughly 50x that of the sample being separated.
