Solid phase extraction cartridges, Bond Elut™ SCX
Supplier: VARIAN
Bond Elut™ SCX is a strong cation exchanger with a very low pKa. Although the pKa is similar to Bond Elut™ PRS, the presence of the benzene ring in the functional group increases the potential for non-polar interactions. This non-polar characteristic becomes particularly important when conducting ion-exchange from aqueous systems, where selectivity towards compounds exhibiting cationic and non-polar character is seen.

Solid phase extraction cartridges, Bond Elut™ DEA
Supplier: VARIAN
Bond Elut™ DEA bears some resemblance to Bond Elut™ NH₂ in its properties but with a slightly lower capacity as an anion exchange sorbent. DEA has a moderately non-polar character due to the alkyl side chains on the amino functionality. These groups still afford a medium level of polarity, higher than C₈ but less polar than C₂ or CN-E.
