Description
Description of Propanesulfonic Acid Strong Cationic(PRS) Solid Phase Extraction (SPE) Cartridges
The PRS propanesulfonic acid strong cationic solid phase extraction (SPE) cartridge is a strong cation exchange type extraction cartridge with propanesulfonic 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.
