    The amount of silica gel depends on the Rf difference of the compounds to be separated, and on the amount of sample. For n grams of sample, you should use 30 to 100 n grams of silica gel. For easier separations, ratios closer to 30: 1 are effective, for difficult separations, more silica gel is often required.
