Ion-Exchange PSA SPE Cartridges

Mechanism of action: PSA
Particle size: 50-75μm
Average pore size: 100 Å



Description of Ion-Exchange PSA (ethylenediamine-N-propyl) Solid Phase Extraction (SPE) Cartridges

The PSA (ethylenediamine-N-propyl) filler is similar to NH2 with weak anion exchange and normal phase retention. The two amino groups of PSA (pKa 10.1 and 10.9, respectively) provide greater ion exchange capacity and are capable of extracting polar compounds by hydrogen bonding. In addition, PSA forms complexes with metal ions that retain certain metal ions.


Larger exchange capacity than NH2
Effectively remove multiple interference components from food


carbon content: 8%
Specific surface area: 500 m²/g
Particle size: 50-75 μm
Average pore size: 100 Å


PSA packing allows you to load SPE cartridges yourself to meet a wide range of application needs, including:
Detection of sedatives in body fluids.
Removal of fatty acids (such as oleic acid, palmitic acid, linoleic acid) that affect the detection of food matrices, organic acids, partial pigments, metal ions, carbohydrate interferences, etc.
