Normal Phase Diol SPE Cartridges

Diol solid phase extraction (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 electrode Sex compounds.


Description of Normal Phase Diol Solid Phase Extraction (SPE) Cartridges

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.


Can replace silica gel cartridge and avoid interference with alkaline impurities
Positive phase or reversed phase retention by the solvent ratio

Application of Normal Phase Diol Solid Phase Extraction (SPE) Cartridges

Analysis of pigments, phenols, and phospholipids in vegetable oils
Detection of drugs and metabolites in biological matrices such as urine
Separation and purification of glycan mixture
