Bond Elut DEA (diethylaminopropyl) can be used as both a weak anion exchange sorbent with aqueous samples or as a polar sorbent with nonpolar organic matrixes.

• Weak anion exchanger
• More polar than C8 but less polar than C2 or CN
• Alkyl side chains confer moderately nonpolar characteristics

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 nonpolar 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.
