Ion-Exchange PRS SPE Cartridges

Ion-Exchange PRS SPE Cartridge is a big cation exchange sorbent with great retention for basic compounds. As the intensity of cation exchange cartridge, PRS SPE chromatography cartridges are really suitable for weak cation like pyridine compounds which could get a high recovery rate. And it is an alternative to SCX if the sample of the non-polar compound can’t remove by using the latter.


Description of Ion-Exchange PRS SPE Cartridges

PRS SPE chromatography cartridges are strong cation exchange extraction cartridges based on silica gel. The bonded functional group is propyl sulfonic acid, which is slightly less acidic than SCX (benzene sulfonic acid).
