WebbIn particular, slurry-packing is most suitable for packing silica-based packing materials with small particle sizes ( ≤ 20 µm). Packing adaptors are not suitable for elongating column length, as they are auxiliary parts developed for slurry-packing. The inner diameter of the packing extensions should be the same size as that of the column. Webbnon-polar solvent or making slurry of crude product in silica gel is recommended. • Load diluted solution or slurry (Fig. 5) of crude product into packed column using Pasteur pipette or a funnel. When loading the column minimize the disturbance of the column by charging the products on to the walls of the column.
