Recommended Storage Condition for Functionalized SiliaSep Cartridges

> back to Application Notes

A single use (1 injection run) of Amine, Cyano, Diol, SAX, SCX, WCX and reversed-phases cartridges is usually recommended as the results of a reused cartridge cannot be guarantied. Indeed, while it is possible to elute “nearly all the product” from silica, some impurities may remain at the end of each separation. If the cartridge is not fully cleaned, this remaining material may reduce the purification effectiveness and / or these impurities may elute in a subsequent run. In some cases, proper storage could allow functionalized silica gel cartridge to be reused. A proper storage for each column is described in this Application Note.
