Mechanism of action: PRS
Particle size: 40-75μm
Average pore size: 100 Å
Ion-Exchange PRS SPE Cartridges
Description
PRS SPE Cartridges
The PRS propane sulfonic acid strong cationic 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 SPE cartridges, when non-polar components in the sample matrix interfere, PRS can be used for extraction.
Characteristics of PRS SPE Cartridges
High recovery rate for pyridines
Single separation mechanism, no secondary interaction
Parameters
Carbon content: 4.5%
