Question 1 1.1 Silica gel chromatography: This is known as the stationary phase in column chromatography. Firstly‚ the tapered exit of the column is sealed using porous material. This porous material serves as support for the packing material‚ and prevents it from exiting the pipe. Thereafter‚ silica gel is compacted into the glass pipe to make the separating column. In finishing preparation of the column‚ the solvent which is used as the mobile phase is then passed through the dry column. Then the
