PRS SPE Cartridge
Extracting weak bases in biological fluids
Finetech® PRS is a strong cation exchange sorbent with excellent retention for weakly basic compounds.
PRS shows unique selectivity owing to the absence of non-polar interactions. It is an alternative to SCX if non-polar components in samples couldn’t be removed by using the latter.
High recoveries for pyridinic compounds
Simple retention mechanism, no non-polar interactions
