However, when flushing these columns with strong organic solvent, the column packing materials which exposed to some organic solvents will swell and column bed will be damaged. The swelling degree of the packing materials depends on the cross-linking degree of the polymer. Generally, the polymer whose cross-linking degree is higher than 8-10% has better physical stability. The shrinkage in the aqueous solution and the expansion in the organic solvent are both small, but limitation of using condition still need to be paid attention. 02 Daily Flushing 03 Regeneration and Flushing 04 Precaution 1.
