Copure PRS SPE Cartridges

Format: 100mg/1ml 100/box

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.

Available in different formats.

  • High recoveries for pyridinic compounds
  • Simple retention mechanism, no non-polar interactions

Carbon content: 4.5%
