Packing DAC Columns Using SiliaSphere Spherical Silica Gel

Moving on from analytical columns method development to pilot or production scale has always represented a challenge. So too has the optimization of the packing procedures for large ID columns. Most columns for early method development are supplied prepacked by column manufacturers at relatively low costs.
In order to keep these costs minimal as well as for convenience and availability reasons, most process scale column users have elected to integrate Dynamic Axial Compression (DAC) column production in their own facilities whenever they need large ID columns (> 21.2 mm).
