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.
