Ion Exchange

Enjoy now the use of our analytical support for ion exchange, a purification of molecules method based on ionic (Cationic or anionic) interactions.

In that way, positive molecules are linked to a negatively charged sorbent and inversely for the negative molecules. The elution is done with an increasing salt concentration gradient so that the less charged molecules are eluted first.

To fit with all your purification needs, we offer 3 kinds of remarkable analytical support:

• Silica: for the highest resolution
• Polymere: for the largest range of pH (1 - 12)
• Cellufine: reticulated Cellulose based resin
