Answer (excluding residual solvent and other volatile substances in the stationary phase)
Removing the residual solvent and other volatile substances in the stationary phase
Remove the residual solvents and other volatile substances from the fixed phase to make it uniform.
The newly prepared packed column must undergo aging treatment before use, in order to remove residual solvents, low-molecular-weight stationary phases, and low-boiling-point impurities from within the column, thereby ensuring that the stationary phase is coated more evenly and firmly on the surface of the support
