Notes of use of Column Packing
-
Due to their low bulk densities, Glass Raschig rings are particularly suitable for packing glass columns.
-
Generally, the ratio of Column diameter to packing diameter should not be less than 8:1
-
When using smaller packing size, a small layer of larger packing should be used on packing support, to prevent the smaller packing falling through.
-
In vacuum application and applications involving high vapour velocities, packing may be lifted and may damage to other parts. To prevent this, a packing retainer (PTFE perforated plates) should be used above the packed section.
