Diol SPE cartridge weak anion exchange, the diol-based filler has similar silica gel retention and less acidity, carbon chain provides additional hydrophobic interaction, so it can be used as a normal phase or reverse phase absorber, extraction extracting polar compounds.
Diol is a medium-polarity adsorbent that binds polar bonded phase diol groups (-Si(CH2)3OCH2CH(OH)CH2OH) on a silica gel matrix.
Diol is similar to unbonded silica gel and tends to have strong hydrogen bonding. It is often used to extract polar samples from non-polar solutions.
If a silica gel cartridge is used, the acidity of the silica gel leads to the retention of alkaline impurities and can be replaced with a Diol SPE cartridge.
