Preparative Chromatography - Radial Flow Chromatography > Page 64
The method used for packing radial columns is depicted in figure 33. The packing is prepared in the form of a slurry and is pumped directly into the column between the two frits. The column exit to the detector and fraction collector is closed, and, as a result, the slurry solvent passes through the outer frit and exits via the normal mobile phase inlet port. The columns are very easily unpacked by adopting the reverse procedure.
