Copure® PRS SPE Cartridges

Extracting weak bases in biological fluids

Copure ® 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
