Ion-Exchange PRS SPE Cartridges

Mechanism of action: PRS
Particle size: 40-75μm
Average pore size: 100 Å


Description of PRS SPE Cartridges

The PRS propane sulfonic acid strong cationic solid-phase extraction (SPE) cartridge is a strong cation exchange type extraction cartridge with propane sulfonic acid bonded silica as a filler, which has good retention ability for weakly basic compounds.
There is no non-polar secondary action in the PRS and thus has a unique selectivity. When using SCX, when non-polar components in the sample matrix interfere, PRS can be used for extraction.
