How can Ion Exchange HPLC columns be cleaned and regenerated?

This is our recommended regeneration procedure of Ion Exchange packings, anion and cation exchange (WCX, SCX, WAX, SAX):

Flush the column with 20 column volumes of the same eluent,
But double the buffer concentration
Follow the regeneration protocol forRP packings
Flush the column with 20 column volumes of water
Equilibrate the column with the original conditions
